Hi, I'm Tijmen.
I like to make things and to find simple solutions to real problems.
I graduated cum laude from TU Delft, specialising in Cyber Security and Machine Learning. Since then I've built AI products, research tools and now my own game.
Most of my week goes to full-time management of world-famous skateboarder @surfsterre: partnerships, planning, travel, content and everything else behind the scenes.
I'm also a professional windsurfer. When I'm not on the water, I'm programming. It started as a hobby and never stopped. My current projects are Marsheez, a party brawler coming to Steam, and CAICH, an AI coaching platform.
