Frontend developer from the Netherlands with a thing for building things that probably shouldn’t exist. By day I write React and TypeScript at KNMI. By night I build eyebrow-controlled Tetris, webcam duck hunts, AI experiments, Arduino gadgets, Flutter apps, 3D-printed stained glass, and chocolate molds from my 3D printer.
