I replaced Tailwind with StyleX. The site didn't get faster.
I migrated a site that already scored 100 on PageSpeed to StyleX, measured the result, and found the real performance win somewhere else.
I'm a Principal Engineer with 16 years of front-end development experience, delivering high-performance web and mobile applications. Today most of my work is AI-native: designing agent harnesses, orchestration, and the tooling that makes coding agents reliable.
My specialization spans React and Node.js architectures, performance and observability, and agentic development: skills, evaluation loops, and orchestration across Claude Code, Cursor, Codex and Gemini CLI. I focus on accessible, user-friendly experiences through design systems and web accessibility.
Beyond technical work, I contribute to the community through mentorship, pair programming, and open source, including projects focused on AI and agent tooling. I also speak at tech talks and on podcasts.

We took a storefront from 15s to 3s on throttled 3G and conversion went up 45%. What to measure, where the time really goes, and why the biggest wins are usually deletions.
