New year, new impact. I have some freelance capacity:

I can help your team get effective. If it’s about coding/work/team standards, send me a message.

Recently, I was hired as Lead Dev, Workflow Coach, Engineering Manager, Accessibility Program Manager and clients were happy.

What's new in view transitions (2025 update)  |  Blog  |  Chrome for Developers An overview of what changed for View Transitions in 2025

A lot has happened since Chrome shipped Same-Document View Transitions in 2023.

In 2024 we shipped Cross-Document VTs, added refinements such as `view-transition-class` and VT Types, and also welcomed Safari in adding VT support.

And this year … well, I wrote a post summing it all up.
