I need a seasoned full-stack professional—ideally someone with at least six years in the field—to take a mobile concept from idea to App Store and Google Play release. The job covers everything: crafting a polished user interface for both iOS and Android, wiring it to a robust backend, setting up the database, integrations, and basic cloud deployment. Because the assignment spans the entire stack, you should already be fluent in at least one modern cross-platform framework (React Native, Flutter, or similar), comfortable with REST / GraphQL APIs, and able to manage authentication, push notifications, and in-app data sync. Clean, maintainable code and clear communication are essential. When you respond, focus on your relevant experience—highlight previous cross-platform apps you’ve shipped, the stack you used, and any metrics or user feedback that show real-world impact. Links to live apps or repositories help me evaluate fit quickly. Deliverables • Fully functional mobile app for iOS and Android • Backend and database configured and deployed • Source code in a shared repository with commit history • Short hand-off document covering build/run instructions, environments, and release steps I’ll review proposals as they arrive and reach out if your background matches the depth and breadth this project requires.
