During May 2026, contributed targeted documentation enhancements to the pmndrs/jotai and microsoft/fluentui repositories, focusing on improving developer experience and onboarding. Updated Next.js documentation in pmndrs/jotai to clarify browser storage usage with atomWithStorage and createJSONStorage, addressing SSR hydration risks when accessing localStorage and sessionStorage. In microsoft/fluentui, revised icon toolkit documentation to reflect deprecation and outlined practical alternatives for font-based icons in web applications. Leveraged JavaScript, TypeScript, and Markdown to align usage patterns and examples across both projects, ensuring consistency and actionable guidance for front end developers working with React and modern documentation tooling.
