Tania's philosophy—"Everything on this site is written by me, not AI"—sets the gold standard for authentic technical education. Building websites since 1998, her deep-dive guides on React, Vue, CSS, and command-line tools make complex topics approachable. Her open-source projects (TakeNote, New Moon editor theme) and content-first approach to learning influence how we think about documentation and knowledge sharing. Tania's commitment to human-centered technology aligns with our values.

React's declarative component model and hooks revolutionized how we build UIs. With 240,000+ stars, 1,720 contributors, and 29.8+ million dependents, React powers ONE's interactive islands. We pair React with react-dom for server-side rendering on Cloudflare's edge using `react-dom/server.edge`.
