    I’m launching an online evangelic radio show and need the full technical and production framework put in place.

    I’m building a new marketplace focused exclusively on physical goods and need an end-to-end development partner who can deliver both a responsive web app and companion mobile apps for iOS and Android. The platform must feel seamless no matter how users access it, so shared business logic and a single back-end are important. I’m flexible on the exact tech stack—React + , Vue, Flutter, React Native, or similar—provided the result is fast, secure, and maintainable. Key features to include: • User profiles with onboarding, settings, and order history • Product reviews with star rating and basic moderation tools • Secure payment system that supports major cards and digital wallets, with escrow or hold-release logic Acceptance criteria 1.

    "Looking for a Chennai - India based Developer" We need an end-to-end system that lets my fitness club run smoothly while giving members a polished mobile experience.

    I need a full-featured ride-sharing and pooling application built for both iOS and Android. The service is designed around shared trips only, so every screen should guide users toward combining routes rather than booking a private cab. For riders I must see live vehicle locations on an interactive map, smooth in-app payments (card, wallet, Apple Pay/Google Pay, etc.), and the chance to rate and review every completed journey. Drivers, on the other hand, should receive pooled-ride requests in real time, view the optimal pick-up order, navigate turn-by-turn, and track daily earnings from an in-app dashboard. A separate administrator panel will let me onboard drivers, monitor live trips, settle disputes, push notifications, and export ride analytics. Deliverables • One codebase (...

    I want a full-featured social networking app built exclusively for Android. The core experience must allow users to create and edit profiles, exchange real-time messages, and browse an engaging content feed. Each of these three functions—profile creation, messaging, and feed consumption—has equal priority for the first release. You will handle everything needed to get a production-ready APK into Google Play: clean, well-documented Android code (Kotlin or Java), integration with a lightweight yet scalable backend of your choice, and a simple but modern UI that follows current Material Design guidelines. Authentication may start with email/password; social sign-in can follow in a later milestone. At hand-off I need: • Compilable source code with clear build instructions ...

    I’m building the first “AllTrails-style” guide dedicated to obstacle-course racing (OCR) training spots and need a production-ready mobile application that runs smoothly on Both iOS and Android. The core experience hinges on a live map (Google Maps API or comparable) where users can drop pins, attach geo-tagged photos, write descriptions such as “Great for rope climbs—public park with pull-up bars,” rate the spot, and tag it with OCR-specific attributes like grip strength, endurance, or mud terrain. Beyond discovery, the app must feel social. Logged-in athletes should be able to comment, favourite, post challenges (“Beat my time at this spot”), and build simple public profiles. Powerful filters—difficulty, obstacle type, proximity, use...

    I already have the complete Android source code and now need it visually overhauled. The task is a pure reskin: swap in my new logo, colors, icons, splash screen, and any other branding assets I supply. No deep feature rewrites are planned, but you may adjust XML layouts or minor Java / Kotlin snippets if that’s what it takes for the new design to fit cleanly. The project is built in Android Studio, so please be comfortable working with its latest stable release, Gradle, and typical asset pipelines. When you hand the work back, I expect: • Updated source code compiling without errors • A signed AAB/APK ready for Google Play submission • A brief changelog so I can track exactly what was touched If you can turn this around quickly while keeping the codebase tidy, ...

    I need a polished e-commerce application that works seamlessly on both iOS and Android. The storefront should showcase my full product catalog, allow quick, intuitive search, and let customers create accounts or sign in with the usual social or email options. Once users are ready to purchase, the checkout flow must connect to a secure, widely used payment gateway so transactions clear without friction. I value a clean UI, fast load times, and code that scales—preferably built with a single code-base framework such as Flutter or React Native, though I’m open to native development if you can explain the long-term advantages. Deliverables • Fully functional iOS and Android builds • Admin-side access to add, edit, or remove products and view orders • Integr...
