Estelle Weyl is a senior technical writer and community engineer in San Francisco with two decades of hands-on experience building standards-compliant, accessible, and high-performance front-end UIs. She authors and maintains documentation for MDN/Open Web Docs, contributes to W3C CSS Working Group drafts, and improves MDN learning content with a focus on ARIA and modern CSS examples.
