From role-mobile
Guides mobile performance optimization for iOS/Android apps: 60fps rendering, memory leak detection/management, battery efficiency, startup time reduction (cold/warm/hot), image loading (Glide, SDWebImage, Coil), profiling with Instruments, Android Profiler, Flipper. Use for frame drops, ANRs, OOMs.

- Diagnosing frame drops, jank, or ANR issues on iOS or Android
Provides React Native performance optimization guidelines for FPS, TTI, bundle size, memory leaks, re-renders, and animations. Guides Hermes optimization, JS thread blocking, bridge overhead, FlashList, native modules, and jank debugging.
Diagnoses and optimizes React Native app performance: slow startup, janky scrolling, stuttering animations, large bundles, high memory.
Optimizes React Native apps with guidelines for FPS, TTI, bundle size, memory leaks, re-renders, and animations. Helps with Hermes, JS thread blocking, FlashList, native modules, and frame drops.
