Overview

Currently at ASML, where I lead user research with a team of 55. Ran 138 usability sessions and turned them into a research repository. Built a component library 28 engineers ship with every day. Before that: Novartis and Philips. Most at home with usability testing and jobs to be done. Coffee nerd.
