Senior Frontend Developer · AI-Native Engineer · Creator of No-JS.dev
Everyone's coding JavaScript. I built a reactive framework that needs none.
Senior Frontend Developer with 20+ years shipping scalable SaaS to global teams. Creator of No-JS.dev, an HTML-first reactive framework with zero JavaScript, zero build step, and zero dependencies. Deep in Angular/RxJS/NgRx with serious automated testing, and building daily with Claude Skills, AI Agents, and the Anthropic API, while keeping full ownership of every architecture decision.
