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...

Necesito desarrollar una aplicación nativa para Android cuyo núcleo sea un sistema de autenticación de usuario sólido y fácil de mantener. La primera versión debe permitir que un nuevo usuario se registre con correo y contraseña, inicie sesión, recupere credenciales y mantenga la sesión de forma persistente. Trabajo con Git, por lo que el código fuente debe entregarse en un repositorio privado y estar claramente documentado. Quiero una arquitectura limpia (idealmente MVVM o similar) y dependencias bien gestionadas con Gradle. Aprecio el uso de Jetpack Compose, aunque acepto XML si explicas tu elección. Acepto Firebase Authentication, Auth0 u otra solución siempre que justifiques la selección, p...

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 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 need an Android-only time management app whose core purpose is to keep users on schedule through smart notifications and reminders. The flow is simple: a user sets a task, defines a deadline or ideal start time, and the app nudges them at just the right moments. You are free to choose the framework (native Kotlin/Java or a cross-platform option that still compiles cleanly for Android) as long as the final build is stable, responsive, and Play-Store-ready. I’ll want both an installable APK and full, well-commented source so I can iterate later—potentially adding task scheduling or full time-tracking modules down the road. Key expectations • Clean, modern UI that feels intuitive on current Android versions • Reliable foreground and background notification ha...

I want a clean, lightweight Android application that my field sales team can open, log in with their company email and password, and capture secondary-sales orders on the spot. Two roles matter to me: • Salesman – enters demand, adjusts MRP-based discounts, and submits the order. • Manager – reviews or edits what the salesman submitted and can pull quick reports. The core flow is simple: after login the salesman selects the customer, adds products with quantities, sees the auto-calculated total, applies any discount by percentage or value, and taps “Generate Order”. The app must immediately create a branded PDF containing all line items, MRP, discounts, net values, date/time, and the salesman’s details. That PDF should save locally and be shareab...

I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

I run an internal up-skilling program for fresh graduates who have just joined our team and I’m looking for a trainer who can take them through AI agents, Python programming, and core Machine Learning concepts while walking them through a demo chatbot and one or two small sample applications. The classes will be online on Fridays, Saturdays, and Sundays, any 1–2-hour slot you prefer between 6 pm and 9 pm IST. A strong mix of digital whiteboard explanations, concise PowerPoint slides, and live screen-sharing is essential so the learners can both follow the theory and code along in real time. For each session I will need: • well-structured slide deck or whiteboard notes • the live notebook / script you write during class • a short, working demo project or e...

I’m ready to launch a proprietary AI-driven builder inspired by Lovable and Base44. The vision is a web-based platform where non-technical users can assemble complex assets in minutes while the system quietly orchestrates the heavy lifting—model selection, training, and deployment—behind the scenes. You’ll guide the entire build: architect the cloud infrastructure, code the core engine, design an intuitive front-end, and wire everything together with robust APIs. Think drag-and-drop creation, reusable templates, realtime previews, and seamless connections to popular third-party tools so that users can publish or integrate their results without touching code. On the AI side I’m open to the mix you feel best suits the goal—classical machine-learning pip...

I have two signed Android APKs that share the same brand: a Chinese-language build that already handles user registration smoothly, and an English-language build that currently lacks this flow. My goal is to extract every user-management API call from the Chinese APK—endpoints, headers, payload structures, encryption or signing logic—and transplant that functionality into the English APK so both variants register users in exactly the same way. What I can provide: • The release APKs for both language versions • Valid test accounts and server access for live registration checks • Any additional assets the Chinese build relies on (native libraries, certificates, config files) What I need from you: • Decompile, inspect and document the Chinese APK (jadx, a...

I’m looking for an experienced software developer to take the lead on a desktop application I’m planning to release. The project centres on creating a robust, user-friendly program that runs smoothly on Windows and macOS, with clean architecture and maintainable code. Key responsibilities will include: • Gathering and refining requirements with me in short discovery calls • Designing the application structure, database layer, and UI framework • Writing, testing, and documenting the code (preferred stack: C#/.NET or JavaFX—open to your suggestion if you can justify it) • Packaging the final build for easy installation and future updates I value regular progress demos, well-commented source files, and clear communication. If you have a portfolio of pre...

I’m ready to commission an Android-only audiobook application and need an experienced mobile developer to take it from concept to Google Play release. At its heart, the app must stream and locally cache audiobooks, let listeners drop unlimited bookmarks while they listen, and handle one-tap downloads for fully offline playback. Monetisation is essential: new titles will be sold individually, so please wire the catalogue to Google Play Billing for in-app purchases. Authentication will be straightforward email-and-password login—either a lightweight back-end you spin up or a Firebase Auth integration works for me so long as it’s secure and quick for the user. Core flow I have in mind • Launch ➜ user signs up or logs in • Library screen lists available au...

I want to bring a brand-new social networking idea to life on Android. The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...

I own a licensed copy of the Dooo Movie Streaming Android source code and now need it running live on Google Play. The current project refuses to compile because of dependency issues and an outdated SDK. Here’s what I need from you: • Open the project in Android Studio, upgrade it to the latest stable SDK/Gradle versions, and cleanly resolve every dependency conflict so the APK builds without warnings. • Configure package name, signing key, Firebase/Ad-mob (if present in the code), and any other runtime settings the template requires. • Run a full device/emulator test to confirm login, streaming, search, and push-notification flows all work exactly as in the template demo. • Generate release AAB/APK and guide me through—or directly handle—th...

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...

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...

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 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...
