I’m Jonah, a frontend developer from Rotterdam.

I currently work at B.made, a dutch digital agency based in Rotterdam. At B.made I build websites and apps using Vue.js and React Native. Previously I worked at Dept and Keylane.

In my spare time I create websites and webshops as a freelance developer. Mostly build using WordPress and React.
