Hello. My name is Sem Goedknegt. I'm an interface designer and frontend developer working from Puttershoek, The Netherlands. I co-founded Ivaldi, which was acquired by ReMark. Now I make things people want to use because they're fun & convenient.

I've built more WordPress themes than I can count, spent years doing Ruby on Rails, and still believe the best interface is the one you barely notice. I take on the occasional project, mostly when it involves making something simpler than it was.

Say hello at sem@knegt.io.
