Welcome.
Making the web performant and accessible is my passion.
All of my content is tailored to performance, user experience (UX) &
security. See all of my principles.
My work experience and interests include React and Node.js, SQL, micro‑frontends
(MFEs). I love optimizing Core Web Vitals (CWVs), CSS & JavaScript runtime performance.
Right now, I work as a Senior Performance Engineer on thousands of websites
built with Framer.
In the past, I've co-founded an eSports company and have created multiple
browser extensions for Google Chrome, used by more than 65.000 people daily.
