Sjoerd Beentjes — senior front-end developer

Hi! I build for the web, and I’ve been doing it for

eight years at a front-end studio in Amsterdam & Delft.

I care about the things you can’t always see: accessibility,

performance, and interfaces that stay clear no matter who’s using them.

⌖ Based in Castricum, The Netherlands.

Try work to see what I’ve made, or contact to say hi.
