Cross-Platform Mobile UI Build

I’m ready to move quickly on a polished, responsive front-end for a brand-new mobile app that must launch on both iOS and Android simultaneously. All server-side endpoints are already in place, so your focus will be the client-side experience—navigation flow, screen layouts, graceful states, and smooth animations.

You’re free to suggest the most efficient toolkit for a single codebase (React Native, Flutter, Kotlin Multiplatform, or anything comparable) as long as it delivers native-feeling performance on each store. The design system isn’t locked down yet; I’ll share low-fidelity wireframes and brand colors, and we can iterate together to craft a modern look that feels at home on both platforms.

What I need from you:
• Pixel-perfect implementation of the provided screens, wired to mocked data at first and then to live endpoints I’ll expose.
• Device-agnostic layouts that render correctly across phone and tablet sizes.
• Build and signable release artifacts for App Store and Google Play, plus clear setup notes so I can reproduce them locally.
• A concise README explaining project structure, state management choices, and any third-party packages you add.

If you’ve shipped cross-platform apps before and can point me to examples in the stores, let’s talk timelines and get this rolling.
