Cross-Platform Mobile App Development

I need a complete mobile application built for both iOS and Android. While the core concept is already defined on my side, I’m still open to your guidance on refining the feature set, selecting the most suitable tech stack (native Swift/Kotlin, Flutter, React Native, etc.), and shaping an intuitive UI that follows each store’s guidelines.

Your role will cover everything from architecture and coding through testing and deployment. An end-to-end hand-off is important to me, so please be comfortable publishing to the App Store and Google Play and walking me through future update procedures.

Deliverables I will look for:
• Source code in a shared repository
• Compiled builds ready for TestFlight and internal Android testing
• Clear documentation on setup, third-party services, and release steps
• A short hand-over call or video explaining the project structure

If you have a proven track record of shipping stable, user-friendly apps on both platforms, I’d love to see examples and discuss timelines and milestones.
