Worked on the facebook/react-native repository to enhance reliability in cross-platform module loading for iOS and macOS. Addressed a critical issue in the TurboModule loading path by introducing a safety guard within RCTTurboModuleManager, ensuring the getModuleProvider method is verified before invocation. This defensive coding approach prevented silent failures when platform modules were not loaded, specifically resolving a React Native MacOS issue caused by an unimplemented delegate method. Utilized React Native, Objective-C++, and iOS development skills to improve stability and cross-platform parity for TurboModules, reducing crash vectors and support tickets while demonstrating a strong understanding of native bridging and platform-specific challenges.
