React Native UI Modernization

We’ve developed an Android app using Kotlin (for root-level Android services) and React Native (for screens and components).
Backend is complete.
All functionality is fully implemented and working.
Basic UI is already in place.

We are looking for a skilled React Native frontend developer with a strong eye for modern, clean, and professional UI design to:

Redesign the existing UI (all screens) to look next-level and professional.

Keep all the current functionality intact.

Ensure smooth user experience and responsiveness.

Make use of best practices for performance and design.
Requirements:

Strong experience with React Native UI/UX design.

Understanding of Material Design / Modern Mobile Design Patterns.

Must maintain the existing code logic — focus only on visual and user experience enhancements.

Experience with Android (Kotlin) is a plus but not mandatory.
Deliverables:

Complete revamped React Native frontend code.

Must be fully integrated and functional with the existing backend and Kotlin services.

Pixel-perfect and smooth animations/transitions where needed.

Optimized for different device sizes.
