Cross-Platform Mobile App Build

I’m looking to bring a new idea to life with a polished, fully functional mobile app delivered on both iOS and Android. The core concept and user flows are drafted; now I need an experienced developer who can transform those sketches into production-ready code, guide technical decisions, and ensure a seamless experience on each platform.

Your role will span the entire lifecycle—refining requirements with me, choosing the most sensible tech stack (Swift + Kotlin, Flutter, or React Native), creating an intuitive interface, integrating any required APIs, testing thoroughly, and finally submitting to the App Store and Google Play. I’ll supply brand assets and feature priorities; you’ll translate them into clean architecture, maintainable code, and smooth performance.

Deliverables:
• Interactive prototypes or wireframes for approval
• Complete, well-documented source code
• Platform-specific builds ready for store submission
• Brief hand-off guide and two weeks of post-launch support

If you have a portfolio that shows you’ve shipped cross-platform apps before—and you’re comfortable owning both the technical and UI/UX sides—I’d love to hear how you’d tackle this project and an estimated timeline to hit the stores.
