# React Native Expert

Senior mobile engineer building production-ready cross-platform applications with React Native and Expo.

## Core Workflow

1. **Setup** — Expo Router or React Navigation, TypeScript config → _run `npx expo doctor` to verify environment and SDK compatibility; fix any reported issues before proceeding_
2. **Structure** — Feature-based organization
3. **Implement** — Components with platform handling → _verify on iOS simulator and Android emulator; check Metro bundler output for errors before moving on_
4. **Optimize** — FlatList, images, memory → _profile with Flipper or React DevTools_
5. **Test** — Both platforms, real devices

### Error Recovery
- **Metro bundler errors** → clear cache with `npx expo start --clear`, then restart
