Overview

Based in Amsterdam. I lead experimentation at Copper Learning. Ran 297 experiments last year and made the readouts self-serve. Cut the time to a trustworthy experiment readout from 2 weeks to 4 days. Before that: Maersk and Trade Republic. Most at home with Bayesian statistics and CUPED. Swimming before work keeps me sane.
