PROFILE

Yichen Yao

Yic Yao focused on security, dependency management, and CI/CD improvements across microsoft/react-native-macos, microsoft/react-native-windows, and facebook/folly. Over five months, Yic upgraded npm and yarn dependencies to address vulnerabilities, removed deprecated packages to mitigate CVEs, and enhanced release pipeline clarity by introducing release job markers in YAML-based workflows. In Folly, Yic migrated storage types to C++23-compatible constructs, improving long-term maintainability. The work leveraged C++, JavaScript, and YAML, demonstrating depth in full stack development and template metaprogramming. Yic’s disciplined approach reduced maintenance costs, improved build reliability, and ensured compliance with evolving security and compatibility standards across multiple repositories.
