Job description: We’re looking for a senior-level developer who can build high-performance web and mobile applications for a company based in Australia. You need to be product-minded, detail-driven, and capable of owning features end to end. This is not a junior role and not a hand-holding environment. Experience Required: 5+ years in production environments Core Stack Angular (12+) for web Flutter for cross-platform mobile Swift for native iOS development You don’t need to be elite in all three, but you must be strong in at least two and comfortable working across them. What you’ll do Build scalable web and mobile applications Translate UI/UX into clean, high-performance code Architect reusable components and systems Integrate APIs and manage async data flows Optim...

I have an existing backend written in .NET Core that exposes a RESTful API. I now need a hand with two things: expanding the API with a few new endpoints and squashing some stubborn bugs that are affecting current routes. The codebase sits in a private Git repository and builds cleanly with the dotnet CLI. You’ll get a detailed list of the endpoints to add or refactor, the steps that reproduce each bug, and a Postman collection for quick regression checks. Once we agree on the work, simply branch, code, test, and open a pull request. Deliverables I expect: • Updated or brand-new C# controllers, services, and any supporting classes that compile against .NET Core. • Targeted bug fixes with unit tests that prove the issue is resolved. • A brief changelog so I can re...

I need a single WebExtension that runs in both Chrome and Firefox and turns our current manual workflow into a one-click process. Its core job is data collection—capturing information from pages we specify—while also handling the little chores my team repeats every day: filling forms, scraping targeted fields, and kicking off routine browser actions such as page refreshes or button clicks once certain conditions are met. The add-on must connect cleanly to three parts of our internal stack: • our CRM system (REST APIs already documented) • the project-management tool we use (webhook support available) • a central database for long-term storage (PostgreSQL) Please build with the standard WebExtension/Manifest V3 approach so we can maintain a single code...

I need an Android app to control my IoT device over Wi-Fi. The app should allow users to: - Turn the device on/off - Adjust settings - Schedule operations - get present status - device voltage regulation Ideal skills and experience: - Strong Android development skills - Experience with IoT communication protocols, particularly over Wi-Fi - User-friendly UI/UX design - Background in setting up secure connections for device control

I’m putting together a series of college-level workshops and need an expert who can both design and deliver engaging, lab-style sessions on AI, NLP, and machine learning. The audience will be under-grad and post-grad students who already code in Python but have limited exposure to real-world AI pipelines. Scope The program should span three core tracks—an approachable “Introduction to AI & ML,” a set of “Hands-on NLP Projects” that let students build something tangible, and a closing block on “Advanced Machine Learning Techniques” that shows them what’s possible beyond the basics. Because the colleges have explicitly asked for hands-on labs rather than slide-only lectures, your material needs to revolve around live coding, intera...

Hello, I need a custom mobile app that runs on Google Pixel 8 and newer. The app should open the Wire application, go through my entire contact list (500+ contacts), and send the same message to each person individually - no group chats should be created so that recipients remain anonymous to each other. Key features • Automatically navigate to each contact in Wire and send the message. • I select the text manually each time before sending starts. • Built-in log that records: – Message sent to each contact – Any error messages/problems – Exact time of each message sent • Runs entirely on the phone as a standalone Android app without requiring a computer or browser. • Ready to install via APK or Google Play (internal test channel is okay). Techn...

My Android app is fully built and live-tested; what I need now is a reliable developer who can take over the hosting and ongoing management so I can focus on feature ideas rather than infrastructure. Here’s the scope I have in mind: • Set up and configure a stable hosting environment suited to Android back-end services (Firebase, AWS, Google Cloud, or your preferred stack—as long as reliability, scaling, and basic security hardening are covered). • Handle versioned roll-outs and hot-fixes whenever I push new code, making sure updates reach the Play Store smoothly and any migration scripts run without downtime. • Proactively monitor performance, apply routine maintenance, and tune the back-end so the app stays fast and crash-free. all 3 apps are ready...

Jag behöver en skräddarsydd mobilapp som körs på Google Pixel 8 och nyare modeller. Appen ska öppna Wire-applikationen, gå igenom hela min kontaktlista (500+ kontakter) och skicka ett och samma meddelande till varje person individuellt – inga gruppchattar får skapas så att mottagarna hålls anonyma för varandra. Viktiga funktioner • Automatiskt navigera till varje kontakt i Wire och skicka meddelandet. • Jag väljer texten manuellt varje gång innan utskicket startar. • Inbyggd logg som registrerar: – Skickat meddelande till varje kontakt – Eventuella felmeddelanden/problem – Exakt tidpunkt för varje skickat meddelande • Körs helt på telefonen so...

I’m kicking off “Haviasfbee,” a brand-new desktop application that must run smoothly on modern Linux distributions. At this stage I have the core concept and workflow mapped out; what I need now is an experienced developer who can turn that vision into a clean, maintainable application. Here’s the scope as it stands today • Build a native Linux desktop app (GTK, Qt or another proven Linux-friendly toolkit—open to your recommendation). • Deliver a functional, installable package plus full source code in a Git repository. • Structure the project so it’s easy for me to extend later: clear architecture, documented classes / modules, and sensible unit tests. • Provide basic instructions for compiling and distributing the app acros...

I am kicking off Phase 1 of the Expressions app exactly as defined in the signed Phase 1 SOW, Annex B, and Annex B-2. During this phase, the scope includes delivery of the complete server-side orchestration layer, system-level identity locking, and a deterministic AI execution pipeline, fully integrated into a native keyboard operating on both iOS and Android. The keyboard must: • Enforce the system-level identity lock, • Invoke backend AI execution to generate anchor- and burst-style emoji outputs, and • Surface generated results in real time within the keyboard experience. Authentication must rely on Sign in with Apple and Sign in with Google. The application must deny access, or selectively restrict features, when a user’s subscription status is not validated....

I need a very small Android application whose only job is to launch and immediately play a single MP4 video in full-screen. As soon as the user taps the app icon, the video should start on its own—no play, pause, seek bar, or any other controls visible. After the video finishes, the app can simply close or loop; I’m open to whichever is quickest to implement. The MP4 file will be provided. Please package it inside the APK, so the app works offline with no additional downloads. Android Studio, Kotlin or Java, and the built-in VideoView or ExoPlayer are all fine as long as start-to-finish playback is seamless on Android 8.0 and above. Deliverables: • Signed release APK for testing • Complete source code project that compiles in the latest stable Android Studio &bu...

My production Flutter app has begun to misbehave on Android 14, 15 and 16 preview builds. The root cause is obvious: the codebase is still on an older Flutter release and the underlying Android SDK has marched on. I need the entire project migrated to the latest stable Flutter version, compiled against the newest Android SDK, and thoroughly tested so it works smoothly on those three OS versions. The scope is simple but critical: upgrade the Flutter framework and all dependent packages, refactor any deprecated APIs, fix compile-time warnings, and resolve run-time crashes or layout glitches that appear only on the newer Android versions. Afterwards I expect a clean, reproducible build (Android App Bundle) plus a short changelog summarising what was updated and why. Deliverables • Up...

I need an Android social-networking app built from scratch. The core idea is a clean, modern platform where users can register, create profiles, add or follow friends, share text-photo-video posts in a scrolling feed, chat in real time, and receive push notifications. A lightweight admin panel for content moderation is also required. Please deliver: • Full Android Studio project (Kotlin preferred, Java acceptable) with well-commented source code • REST or Firebase backend setup, documented and ready for deployment • Brief UX prototype early in the process and a functional MVP roughly six weeks from kickoff • Clear installation guide and API documentation so I can extend or port it to iOS later Material Design guidelines should steer the UI. I’m happy to su...

I’m building a secure, full-featured e-commerce solution that runs smoothly on iOS, Android, and the Web. The core stack can lean on Python for the API layer, with Java or C++ wherever high-performance modules make sense, but I’m open to a workflow you can justify that keeps code clean, well-documented, and easy to maintain. Core scope The first release must cover user account management (registration, login, password reset, profile editing) and end-to-end payment processing with major gateways. A responsive storefront, basic product catalogue, and an admin dashboard will round out the MVP. UX consistency across mobile and web is essential, and I’d like to see thoughtful error handling, secure data storage, and unit tests from day one. Deliverables for this milestone ...

I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...

I need a lightweight Windows desktop application that lets me handle the everyday paperwork of freight management without fuss. The core flow is simple: I open the program, create or select a client, and immediately start filling out ledger entries that capture shipment details—origin, destination, weight, carrier, cost, and any reference numbers. As those records grow, I want to be able to pull clean summaries and printable reports at the click of a button. Must-haves • A ledger module where I can add, edit, and archive entries. • A shipment tracker that links each ledger line to its current status. • A reporting screen that filters by date range, client, or carrier and exports to PDF or Excel. • Smooth installation on modern Windows machines (Windows 10...

I need an Android app that lets my field-marketing reps see their entire day laid out on Google Maps, record every turn they take, and automatically total the distance they cover. Each sales call is flagged as a Meeting Point marker so the team can tap it, log arrival and departure time, and have the visit counted in their daily report. Core flow • Reps start a “shift”, the app begins GPS tracking in the background and draws the live route on the map. • Every time they reach a preset Meeting Point, the app recognises the stop, time-stamps it, and asks for a quick note or photo. • When they end the shift, the app stores a summary: full polyline of the route, total distance travelled, list of visited Meeting Points, and idle time between stops. A simple d...

I’m ready to move quickly on a native Android app focused on trading. The core idea is to give users a clean, fast interface where they can monitor real-time market data, place trades, and review their portfolio on the go. Here’s what I need from you: • A production-ready Android application written in Kotlin (Java is acceptable if you have a strong case). • Secure user authentication and encrypted storage of sensitive data. • Real-time price feeds pulled from a well-documented REST or WebSocket API that I’ll provide. • Trade execution workflows (place, modify, cancel) with robust error handling. • Responsive UI that follows current Material Design guidelines and looks solid on phones and small tablets. • A concise README and c...

I need a lightweight, real-time chat application built exclusively for Android phones. The core focus is text messaging—no voice calls or media sharing for this version—so the interface and back-end can stay streamlined and fast. Key goals • Smooth one-to-one text conversations with instant message delivery and read receipts • Simple, clean UI that feels native to modern Android versions • Push notifications for new messages when the app is in the background • Secure user authentication (email, phone, or social sign-in—whichever you recommend) • Cloud-hosted database for message storage and basic user profiles You’re free to choose the stack you know best (Firebase, AWS Amplify, Supabase, or a custom REST/WebSocket back-end) ...

Quiero trasladar mi página de inventario a una app Android nativa que trabaje exactamente con la misma base de datos: ni copias, ni sincronizaciones externas, sino conexión directa para que todo cambio se refleje al instante entre web y móvil. El usuario ya ingresa en la web con su correo y contraseña, así que el flujo de autenticación debe mantenerse idéntico en la aplicación. Necesito que la app reproduzca las funciones que hoy ofrece el sitio —gestión de productos, movimientos de stock, reportes y cualquier otra vista crítica— con la misma lógica de negocio y sin perder velocidad. Si en el proceso puedes añadir notificaciones en tiempo real o mejoras de usabilidad, serán bien recibi...

I need a clean, native Android application that works as a focused productivity tool centred solely on task management. The core flow is simple: users create tasks, edit them, mark them complete, and view an always-updated list of what still needs attention. Fast load times, smooth transitions and a clutter-free Material-compliant UI matter more to me than a long feature checklist. Key features and behaviours • Add, edit, archive and delete tasks locally (Room or Realm preferred, but I’m open if you can justify another lightweight on-device store). • Optional grouping or tag system so users can sort their list quickly. • Swipe or long-press gestures for common actions. • Due-date picker with basic notifications. Push is not required at launch; local ale...

I have already wrapped up all product design, UX, and UI work for my new Android app and now I need the engineering muscle to bring it to life. Your main mission is two-fold: first, build system-level battery-optimization enforcement so the app behaves responsibly in the background without being killed by Doze or aggressive OEM policies; second, hook the project into Firebase. On the Firebase side, the app must support Authentication and Realtime Database right out of the gate, with Cloud Messaging for push notifications and Remote Config for on-the-fly feature tuning. For sign-in flows, I only need email-and-password and Google Sign-In. You will be working from a clean, well-commented repository that already contains the complete UI layer. I’ll provide the Figma files, current Gra...

I’m building Mirai Album, a desktop application that lets photographers design complete wedding albums without leaving one streamlined workspace. The program must run smoothly on Windows 10 and Windows 11, install with a single click, and feel at home on modern systems. Tech stack You can take either route—Java (Swing/JavaFX) or Python (PyQt/PySide)—as long as the final EXE is stable and fast. I’ll supply brand assets and preliminary UI mock-ups; you focus on the engineering. Core feature set • Integrated photo-editing tools: filters & effects, precise cropping/resizing, and dependable red-eye removal, all updating in real time even with large JPEG or RAW files. • Intuitive page and spread layout with drag-and-drop, unlimited undo/redo, and liv...

I’m ready to turn a simple game concept into a playable Android prototype and need a mobile-game developer who can move quickly from idea to on-device build. Here’s what I need at this stage: • A runnable Android APK plus complete source files set up in a common engine or native Android Studio project—your choice, so long as it’s easy for me to open and extend. • One short, self-contained level that shows the core gameplay loop with placeholder art and sounds. • Basic UI flow: splash screen, main menu, in-game HUD, pause/restart, and end-of-level summary. • Clean, well-commented code structured for easy future expansion. • Smooth performance on recent mid-range Android phones. I’m flexible on tools—Unity, Unreal, Go...

I need a small, self-contained Android application that runs only on my phone—no cloud, no remote server. The goal is to catalogue dancer profiles so I can show, search, and share them quickly during auditions. Core workflow • Create a new profile with name, age, height, full measurements, and the city the dancer is based in. • Attach multiple photos to each profile (photos are the priority), with the option to add a video clip later. • Browse or instantly search by city; that is my main way of organising the list. • From any profile, tap a button to share it straight to WhatsApp or Instagram without exposing the rest of the database. • Keep everything offline in an on-device database (Room or SQLite is fine). A simple “Backup / Restore&rdquo...

I want to bring a very focused Android app to life: its single goal is to help people relax by letting them browse and play short, soothing sound effects. Think of rain drops, crackling fire, or soft wind—nothing fancy beyond an intuitive catalogue and crisp, uninterrupted playback. Here’s what I need built: an Android application (Kotlin or Java, your choice) whose core functionality is sound playing. The user opens the app, taps a tile or button representing a specific sound effect, and the audio starts instantly. They can pause, stop, or switch sounds without lag. No social networking, e-commerce, or bulky productivity suites—just a clean, lightweight relaxation tool. Deliverables • Complete Android Studio project with well-commented source code • Signe...

I am building an enterprise-grade, stealth monitoring solution dedicated to Android 14 devices and I need a senior security engineer who can take it from proof-of-concept to a production-ready SaaS platform. What the agent must do The core of the job is a lightweight background service that captures user activity—specifically app-usage timelines, every keystroke, and continuous location—even under the new Android 14 background-execution limits. All data has to be streamed in real time, encrypted end-to-end (AES-256 at rest, TLS 1.3 in transit), and made available for remote access from a web console. Zero-root, zero-popup, and zero-battery-drain are non-negotiable. How the platform should feel Think managed SaaS: multi-tenant, horizontally scalable, sub-second ingest for ...

I have a new Web3 idea ready to move from concept to code and I’m seeking an experienced blockchain developer to guide and build the entire solution with me. Because the project is still early-stage, I’m open on the specific chain, tech stack, and even the exact feature set—we’ll define those details together during an initial discovery call. What I do know is that the end product will rely on smart contracts, a dApp front end, and secure wallet interaction, so familiarity with Solidity or similar contract languages, , and modern front-end frameworks is essential. Here’s how I’d like to structure our collaboration: – First, a short technical workshop where you assess my concept, recommend an appropriate blockchain (Ethereum, BSC, Polkadot, or ...

We need a full-stack technical staff member with expertise in Java microservice development (Spring Cloud), message queues (Kafka/RabbitMQ), databases and caching (MySQL/Redis), Linux server deployment and maintenance, Nginx gateway configuration, and distributed system debugging to complete the deployment.

I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. （Developed independently using a non-Java language） The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a small cross-pla...

I’m opening a closed beta on Google Play for my new educational app and need 100 real users to join the tester program, download and install the current build, then exercise it for at least a couple of sessions. The insights I’m looking for focus on overall app functionality, so please keep an eye on how smoothly the navigation flows, how quickly each screen loads, and whether any errors or crashes appear. Because the target audience uses a mix of Android phones and larger-screen tablets, tests must be performed on both device types. To make it easy, I’ll share a private Play Store opt-in link. Once the quota of 100 installs is reached, I’ll close the listing and gather your findings in one structured report. Feel free to supplement written notes with screenshots, ...

I need a focused Android application that lets listeners stream my podcast episodes instantly—no forced downloads, just smooth, background-friendly playback straight from the feed.

I’m embarking on an ambitious project to launch a pair of operating systems — one for mobile devices and one for desktop / laptop computers. I deliberately chose Both platforms because I need a seamless experience across phones, tablets, and traditional PCs, without depending on Android, iOS, Windows, macOS, or any other pre-existing stack. The mobile side will be entirely Custom, so we’re starting from a clean slate and can define the kernel, UI layer, and security model exactly as we want. Here’s the flow I have in mind. First, we’ll specify hardware targets and draft the architecture (kernel type, driver model, boot process). Next comes a minimal viable OS for each platform: the desktop build must boot, recognise core peripherals (storage, networking, disp...

I want to boost awareness of my brand, Sangat bangus, through a dedicated Android mobile app. The core idea is a clean, engaging application that tells our story, showcases key products, and makes it simple for users to share content or offers with their friends.

Deliverables • Production-ready APK plus source code (Kotlin or Java). • All design assets and fonts in edit...

I’m planning to launch a brand-new social networking experience focused exclusively on Android users and I need a skilled developer—or team—to turn the concept into a fully functioning app. Scope of work The job covers everything from initial architecture through Play Store release. You’ll be responsible for designing the UI/UX, building the front-end in Kotlin or Java, creating the back-end (Firebase, Supabase, or another cloud backend you’re comfortable with), and integrating standard social features such as real-time chat, user profiles, newsfeed, push notifications, and media uploads. Clean, well-documented code and a modular structure are essential so the project can scale or later be ported to iOS. Deliverables • Interactive high-fidelity mock...

I’m putting together a corporate head-count tracker and I want to move quickly from concept to a secure, production-ready application. The backend will run on Spring Boot; the frontend needs to be available both as classic HTML/CSS/JavaScript pages and as a richer React interface, so we can serve different devices and gradually migrate stakeholders toward React. Security is essential. I need full user authentication with clear role separation—Admin and User—implemented with Spring Security (JWT or another proven token strategy). Beyond wiring the login flow, I also want advice on best-practice password storage, CSRF protection, and anything else you see fit to lock things down. Where I need your help: • Designing the Spring Boot architecture, setting up entities, r...

I need a full-function Android social networking application built from the ground up. The core idea is simple: let users create accounts, build a profile, connect with others, and share content in real time. I’m looking for a clean, modern UI that takes advantage of native Android components, built with Kotlin or Java in Android Studio, and underpinned by a solid, scalable backend (Firebase, Supabase, or your preferred equivalent). Key goals • Smooth onboarding: email, phone, or third-party sign-in • Personal profiles with editable photo, bio, and basic stats • Post feed supporting text, images, and short video • Real-time likes, comments, and push notifications • In-app messaging or chat to keep conversations flowing • Lightweight admin dash...

I need a Python-based trading program that plugs directly into the Zerodha Kite API and runs end-to-end on live Indian equity and F&O markets. The code must handle three pillars inside a single, well-structured repository: • Automated trading – place, modify, and cancel orders programmatically (market, limit, SL). The engine should be able to run multiple strategies concurrently and execute through Zerodha’s regular and MIS product types. • Market analysis – fetch historical and live tick data, calculate technical indicators on the fly (you’re free to use pandas, numpy, TA-Lib, or your own functions), and generate entry/exit signals according to parameters I will supply. • Risk management – position sizing, max daily drawdown, per-trade s...

AI Assistant Feature Project Description: We are developing an AI Assistant Android app that currently works fine when it’s in the foreground, but stops responding in the background We need an experienced Android and Java developer who can implement a background service or foreground notification-based system so that: The AI assistant continues to run even when other apps are open. It can receive and execute commands from notifications or voice input while running in the background. The app should maintain minimal battery usage and comply with Android’s background execution limits (Android 10+). Key Requirements: Strong experience with Android Services (Foreground Service, WorkManager, BroadcastReceiver, etc.) Java-based Android app expertise (Kotlin is a plus) ...

I have an existing Android APK but no accessible source code. I need the app fully de-compiled, cleaned up, and re-assembled so I can continue development. Once the codebase is restored, I’ll want a few targeted edits—mostly refactoring and minor feature adjustments that we’ll clarify together after you review the decoded project. What I expect from you: • Produce a readable, gradle-based Android Studio project reconstructed from the current APK. • Implement the agreed code changes, then compile and deliver a fresh, working release APK plus signed debug build. • Document every modification so I can pick up future work without hand-holding. You’re free to use jadx, apktool, or any equivalent reverse-engineering toolchain as long as the final pr...
