I need an experienced developer who can take my idea from concept to a fully functional mobile app released on both the Apple App Store and Google Play. The project calls for everything from advising on the most suitable cross-platform framework (Flutter, React Native, or a comparable solution) through to coding, testing, deploying, and providing post-launch support. The core tasks include: • Designing a clean, intuitive UI/UX that respects each platform’s guidelines • Building the complete, production-ready codebase with scalable architecture • Setting up all back-end or cloud services the app might require (authentication, real-time database, push notifications, analytics, etc.) • Preparing and submitting the final builds to TestFlight and internal testing tracks, then guiding the release process for public launch • Supplying thorough documentation so I can maintain or expand the app later I’ll share wireframes, feature priorities, and any third-party API details as soon as we connect. Please let me know which tech stack you recommend, your timeline, and examples of previous cross-platform apps you’ve shipped.
