PROFILE

Yichen Yao

Over six months, contributed to microsoft/react-native-macos, microsoft/react-native-windows, and facebook/folly by focusing on security, dependency management, and CI/CD improvements. Addressed multiple CVEs and governance alerts by upgrading npm and yarn dependencies, removing deprecated packages, and aligning release pipelines for better maintainability. Enhanced build reliability and release clarity through YAML configuration and CI/CD job markers, while migrating Folly code to C++23 standards for long-term compatibility. Leveraged C++, JavaScript, and YAML to implement security patching, template metaprogramming, and full stack development. All changes were validated through automated workflows, ensuring stable, secure, and compliant codebases for downstream teams.
