I’m building a cross-platform mobile application for both iOS and Android and need a full-stack developer who is equally comfortable in Python on the backend and Flutter on the frontend. The core build will revolve around four key features: secure user authentication, real-time push notifications, a smooth in-app purchase flow, and a set of social-media style activities such as posting, liking, and basic feed interactions. On the server side, you’ll architect and code the REST (or GraphQL, if you prefer) API in Python, wire up the database layer, and make sure the authentication tokens sync seamlessly with the Flutter client. On the mobile side, you’ll design responsive UI widgets in Flutter, integrate platform-specific purchase APIs for both App Store and Google Play, and implement notification handling that stays snappy even under load. We’ll work iteratively: an initial usable MVP, followed by feature refinement and polish. Clean, well-documented code, regular progress updates, and test coverage that proves each major workflow—from sign-up to a successful purchase—are expected before we move to the next milestone. If this sounds like your stack, let’s get started.

The $4 budget tells me this is likely a placeholder, so I'll speak to the actual scope. Building auth, in-app purchases, push notifications, and a social feed is a serious project, and getting the purchase flow right alone takes careful work since Apple and Google handle receipt validation very differently on the backend. I'll set up the Python API with FastAPI for the auth and feed endpoints, integrate RevenueCat to unify App Store and Google Play purchases instead of wiring each SDK separately, and build the Flutter frontend with a clean feed UI and real-time notification handling via Firebase Cloud Messaging. One thing worth noting: Flutter's in-app purchase plugin requires platform-specific testing on real devices, so the MVP timeline needs to account for that, simulators won't cut it for purchase flows. 1.

I don't use Python for the backend—my stack is Node.js, Express, or GoLang for API and business logic. The rest of your flow—secure auth, push, in-app purchases, social features—I build with Flutter for mobile and my supported backend. If you’re flexible moving the backend to Node or Go, I can deliver the full stack, including auth tokens, REST API, purchase flows, and real-time notifications. Let me know if adjusting to this stack is an option. If Python is required, not the right fit. Pradeep

Hello, I'd love to help build your cross-platform mobile application. I can develop the Flutter frontend alongside a Python-based backend with a strong focus on performance, scalability, and a seamless user experience. For the MVP, I'll implement secure user authentication, social features (posts, likes, and feeds), real-time push notifications, and in-app purchases for both iOS and Android. The backend API will be designed for clean integration with Flutter, including secure token management and efficient database operations. My approach includes: * Flutter development for iOS and Android from a single codebase. * Python backend APIs (REST or GraphQL based on project requirements). * Secure authentication and session management. * Push notification integration for real-time updates. * App Store and Google Play in-app purchase implementation. * Social feed functionality with scalable database design. * Clean, well-documented, and tested code with regular progress updates. I'll follow an iterative development process, starting with a functional MVP and refining features based on feedback while ensuring each major workflow is thoroughly tested before moving to the next milestone. I look forward to discussing your requirements in more detail. Best regards, Abhishek

Respected Sir, I carefully read your project and understand that you're looking for a full-stack developer to build a scalable cross-platform mobile application with Flutter on the frontend and Python on the backend, starting with an MVP and evolving it through iterative development. My approach is to develop a clean and secure backend using Python with REST (or GraphQL if better suited), PostgreSQL for persistent data, and Redis where appropriate for caching and performance. The Flutter application will feature responsive UI, secure authentication, real-time push notifications, in-app purchases for both Android and iOS, and social interactions such as posts, likes, and feeds. The architecture will be modular and well-documented, making future feature additions and maintenance straightforward while ensuring reliable synchronization between the mobile client and backend. With 5+ years of experience in Flutter, Python, REST APIs, database design, and scalable full-stack application development, I focus on writing maintainable, production-ready code backed by proper testing and documentation. You'll work directly with me—no agency or middleman—ensuring transparent communication, frequent progress updates, and milestone-based delivery. My pricing is flexible depending on the final feature scope and technology choices. Looking forward to working with you! Best regards, Rohan M.

Your project requires more than just connecting a Flutter UI to a Python API — the challenging part is making authentication, purchases, notifications, and social interactions work reliably together under real-world mobile conditions. For the backend, I would structure the API in Python with a clean service-oriented architecture, including secure token-based authentication, database modeling for feeds/interactions, push notification orchestration, and proper test coverage for critical workflows. I can work with REST or GraphQL depending on how dynamic you expect the client-side data consumption to become. On the Flutter side, I can implement responsive cross-platform screens, purchase flow integration for both stores, notification handling, and state management focused on maintainability as the product evolves beyond the MVP stage. For scalability and reliability, I typically design the backend with async processing where needed (notifications, feed updates, purchase events), structured logging, environment isolation, and deployment-ready architecture from the beginning instead of retrofitting later. The iterative approach you described makes sense for this type of application. I can deliver an initial production-ready MVP first, then continue with refinements, performance improvements, and additional social features while maintaining clean documentation and frequent progress updates.

A cross-platform iOS/Android app with a Python backend, Flutter client, secure token auth, real-time push, in-app purchases and a social feed — I build exactly this. I shipped an Event Ticketing SaaS: 50+ REST endpoints, PostgreSQL, Stripe in-app payments, Twilio/email notifications, QR flows, Jest-tested. And a government board platform with Flutter clients on a Node/NestJS backend — RBAC, push, audit logging. How I'd approach yours: a Python REST API with JWT auth synced to the Flutter client, Postgres + Redis for the feed/cache, StoreKit/Play Billing for IAP, and FCM/APNs push. I'd ship a usable MVP first (sign-up -> successful purchase), then refine — with tests proving each workflow. Want me to start the MVP milestone with auth + feed, or the purchase flow first? — Zohaib, AI & Automation Engineer
