    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 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’m building a dedicated Android application that lets users browse, purchase, and instantly access digital products. Think of items such as e-books, audio files, software keys, or any downloadable content that can be delivered straight to the user’s device the moment a transaction is confirmed. What I’m looking for is an Android developer who can take this concept from clean architecture through to launch on Google Play. The core of the job is creating a smooth catalogue and checkout experience optimised for mobile, then handling the secure delivery of the purchased files. Clean code, reliable state management, and attention to UX details (progress indicators, purchase confirmation, download status, error handling) are all important to me because the product is intangib...

    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.

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 already have two complete app concepts: every screen, interaction and asset is designed, documented and ready to hand over. What I need now is the engineering muscle to turn those polished Figma files into production-ready Flutter applications that run smoothly on both iOS and Android. Both apps share a common backend. The REST endpoints, data models and authentication flow are all mapped out, so your focus will be wiring the UI to those services, managing state cleanly and ensuring offline resilience where needed. I expect pixel-perfect implementation of the provided designs, faithful reproduction of the planned user journeys and thoughtful handling of edge cases across devices. Deliverables • Full Flutter codebase for the two apps, structured for reuse of shared components &...
