I'm a frontend developer and Principal UX/UI Engineer at Cube Dev. I make complex products feel clear through thoughtful interfaces and scalable, AI-ready design systems.

I created Tasty and Glaze; lately, I'm also building Akno and Cookbook. Based in Amsterdam, the Netherlands. Photography and music outside of work.
