about

i'm interested in difficult problems.

I'm Julian, a builder from Amsterdam.

I've spent the last few years building software, working with businesses, experimenting with AI, and learning how technology moves from an idea into something people actually use.

Outside technology, I'm a competitive rower. Training and racing at a high level has taught me discipline, adaptability, teamwork, and how much can be achieved when execution matters.

dutch national champion — men's 16 quadruple sculls.
