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 Core Web Vitals, browser rendering
& JavaScript runtime performance, React, CSS, Node.js and micro‑frontends
(MFEs).
Right now, I work as a Senior Performance Engineer on thousands of websites
built with Framer.
To make the web better for everyone, I'm also an active participant of
the W3C Web Performance Working Group.
In the past, I've co-founded an eSports company and have created
