Overview

13 years in software engineering, the last 3 at Nimbus Works, where I lead the developer experience team. Reduced cloud spend on developer experience by 30% in two quarters. Built the experimentation framework 23 product teams use to ship changes safely. Before that: ASML and Booking.com. Most at home with TypeScript and CLI design.
