Worked on the facebook/react-native repository to enhance build reliability and optimize performance for large JavaScript bundles. Addressed a critical build system issue by correcting header search paths in the CXXReact podspec, ensuring consistent cross-environment builds. Later, delivered a feature to reduce memory usage during JS bundle downloads by eliminating intermediate buffer copies, which improved stability and prevented out-of-memory errors on Android. Maintained atomic write behavior to avoid partial bundles and strengthened header parsing for greater resilience. Leveraged Kotlin and Objective-C, focusing on Android development, memory management, and performance optimization to deliver robust solutions for complex build and runtime scenarios.
