A little bit
about me

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.
