Worked on browser compatibility and documentation improvements across mdn/browser-compat-data and rust-lang/rust repositories. Expanded WebAuthn compatibility data to reflect Safari 18.0+ support by updating JSON files and aligning PRF data, ensuring downstream tools accurately represent browser capabilities. In the Rust repository, enhanced UnixStream and socket API documentation by clarifying the default SOCK_CLOEXEC flag and correcting Markdown formatting, which improved clarity and reduced onboarding friction for contributors. Focused on API documentation, browser compatibility, and Rust language features, the work emphasized accuracy and maintainability, addressing developer pain points and supporting better understanding of evolving web and systems technologies.
