About

I am a frontend developer with 5+ years of experience building large-scale web applications and financial products. My work spans Angular, TypeScript, Lit, React and Next.js.

I focus on the parts of the frontend that keep products healthy over time: component libraries and design systems, state management, API integration and performance. I also integrate AI-assisted tooling into day-to-day engineering work.

Alongside my job, I maintain open-source libraries, build mobile apps and write about frontend development on Medium.
