I need a developer who can build a clean, stable Android application that lets users sit for fully-timed mock exams. The core of the project is the timer: each session must start, pause, resume, and submit automatically when time runs out, mirroring a real-world exam environment. For this first release I am only targeting Android, so please use a modern, well-supported tech stack (Kotlin or latest Java with Android Jetpack components). The UI should be lightweight and responsive, leaving room for future additions such as a question bank or analytics—but those extras are not in scope right now.

I have a media-streaming application concept that must run natively on Samsung Tizen, LG webOS and Amazon Fire TV. I need someone who already lives inside these ecosystems: you understand the quirks of each emulator, you know where the documentation falls short, and you can architect a smooth, performant build rather than simply wrap a web page.

I’m building a brand-new tracker aimed at hunters and other outdoor enthusiasts who need to see the location of their harvested game is in real time. The core requirement is straightforward: reliable location tracking that appears instantly on a smartphone and must be as small and light as possible. The idea is that a bow hunter can easily track and find their game after a shot is taken. This would ideally be the most ethical form of locating an animal to ensure that it is not gone to waste. Here’s the functionality I have in mind: • The device gathers GPS coordinates, pushes them to the user’s phone over low-energy Bluetooth, and refreshes quickly enough to feel truly live. • When Bluetooth isn’t possible or range is lost, a secondary short-range...

I want a true Bluebook-style application that lets students sign up with email verification, log in securely, and sit for timed SAT Math sections. The same codebase should compile cleanly for iOS and Android phones as well as native Windows and Mac desktops so students can practise on any device they own. Core flow • Student creates an account, verifies via emailed link, and lands on a simple dashboard. • From there they can launch a full-length math section that mimics official SAT timing, auto-advances after each question, and locks once time expires. • At the end of the session the app instantly scores the attempt, shows the correct answers with explanations, and saves the record for later review. I will supply the question bank in CSV; the app just needs an import rout...

I need an end-to-end slot-booking solution that works seamlessly on iOS, Android, and any modern web browser. The goal is to let people find an available playground, lock in a time, and manage any last-minute changes without headaches—while giving venue owners and my own admins the control they need behind the scenes.

I have a working prototype built in Google AI Studio and I now need to take it from “demo” to a secure, production-ready release on both web and Android. First, I want every credential locked down. Both the API keys and the code itself must be protected: secrets moved to environment variables or Secret Manager, no keys exposed in the client bundle, and the repository cleaned of sensitive commits. A brief security checklist or automated scan that proves the hardening is complete will form part of the hand-off. Next comes a functionality sweep. I’m not sure whether anyone has formally reviewed the code, so plan to step through each user flow, patch breakages, and make sure the app genuinely meets Minimum Viable Product standards. User sign-in must switch to Google Authen...

I am building a new cross-platform mobile product and plan to base it on React Native for the client and Firebase for all backend services—authentication, real-time database, cloud functions, and storage. The project also calls for a polished UI created in Figma before a single line of code is written. While React Native and Firebase are my first choices, I am open to hearing how Flutter or Supabase might add value if you have a compelling case. Scope at a glance • Design: Wireframes through to interactive, developer-ready Figma files that capture the complete user journey. • Mobile: Clean, well-architected React Native code that feels native on iOS and Android, integrates smoothly with Firebase, and is ready for store submission. • Backend: Secure Firebase s...

I have built an app using Lovable, the app is a social networking app concept I need you to export the app from lovable and successfully launch it on the App Store and Google Play.

Beyond the usual social staples, I also want a dedicated “Rotation Pool funds” module that lets groups contribute, track, and rotate pooled money inside the app, so experience with in-app wallets or secure micro-transactions will be essential. Here is how I've done for the initial release: • iOS and Android builds written in a shared codebase where practical (React Native, Flutter or similar cross-platform stack is fine, but I’m open to native if y...

I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version...

I am looking for a developer who can turn my idea for an Android-only social networking app into a polished, launch-ready product. The core experience should let users register quickly, build a profile, connect with others, share posts (text, photo, or video), react or comment, and chat in real time. A clean Material design, smooth performance on recent Android versions, and push notifications are essential. I plan to monetise later, so the codebase needs to be structured for easy integration of ads or in-app purchases. If you are comfortable working natively in Kotlin or Java and have handled cloud back ends such as Firebase, Supabase, or a comparable stack, your expertise is exactly what I need. Security best practices, scalable database design, and simple analytics hooks all matter to ...

I already have full, working source code for an e-commerce application on both Android and iOS. No new features are required right now—I just need clean, release-ready builds.

I want to launch a non-custodial crypto wallet that covers the essentials from day one. Users must be able to send and receive coins or tokens, browse a complete transaction history, and restore access at any time through a secure backup flow (seed phrase or encrypted file). The first release targets Android and a browser-based version. Feel free to use Kotlin, Flutter, React Native, or similar for mobile, and React/ (or comparable) for the web client, so long as the codebase is clean and well-documented. Security should follow a solid “standard” approach: client-side key generation, AES-256 encrypted private keys, optional PIN/biometric unlock, HTTPS everywhere, and no server-side custody. Compliance with common audits or libraries (e.g., WalletConnect, ) is welcome but not...

I’m building a full-stack, fully secure money-exchange platform that spans Android, iOS, and a responsive website. The public landing screen must fetch and display up-to-the-second buy/sell rates even for guests, then invite them to sign in.

Once inside, customers need a clean dashboard where they can: • place buy orders • place sell orders • review a complete, filterable transaction history Behind the scenes I’ll need an admin console that lets me adjust spreads manually or, at the flip of a switch, pull live forex data from an API (feel free to recommend the most cost-effective feed).
