01 / aboutAboutwho & what
A bit about me

I'm an ML engineer based in Amsterdam. I currently lead ML at Merqato — demand and supply forecasting for the fresh-produce industry — after four years on the founding data science team at Source.ag, where I built yield forecasting models and a first-of-its-kind digital twin for greenhouses.

Outside of work I build small full-stack apps, AI tooling, and the occasional game. Different surface, same instinct — work the problem, then ship it.
