After graduating, I started working at various companies before ending up at Yoast. Besides developing in PHP, JavaScript and various other languages, I also like to spend my time on playing video games and card games, traveling and watching movies. I’m also one of the organizers of a local PHP meetup group, NijmegenPHP.

At Yoast, I’m assisting the development team by expanding and improving the Yoast plugins.
