Implement and integrate native modules using Java/Kotlin, Swift, and XML.
Work on hardware-level features (microphone, speaker, display, etc.), including permission handling.
Implement push notifications and background processing features.
Keep the app compatible with the latest Expo and React Native versions.
Optimize the app for performance, memory usage, and build size.
Manage state and API interactions using Redux Toolkit & RTK Query.
Integrate Streaming APIs and WebSockets for real-time functionality.
Integrate Stripe Payment Gateway and Clerk Authentication.
Implement email notification systems.
Debug, optimize, and deliver production-ready builds.
