I build creative and accessible websites from scratch, completely tailored to your design.

Whether you need me to build your entire website, or only a part of it, I can work in any (modern) frontend stack and with- and without a team.

I make sure your website is accessible, performant and easy to use.

Not sure how to introduce new techniques without disrupting your workflow or overwhelming your team?

I help companies adopt modern front-end practices in accessibility, motion, and creative development overall. Starting with a practical audit and continuing through implementation, talks, and workshops.

I talk about how I think we should build for the web, focussing on where design, code, and accessibility overlap.

My talks are often about motion and interaction, but accessibility is also an essential topic.
