- Translate complex UI/UX designs into fluid, responsive interfaces using Styled Components or Tailwind CSS, with a focus on 60fps animations using React Native Reanimated.

- Identify and resolve performance bottlenecks, memory leaks, and slow rendering issues using tools like Flipper, React Profiler, and Xcode/Android Studio instruments.

- Architect robust state management solutions using Redux Toolkit, Zustand, or React Query.
