I build developer tools at Microsoft — currently the Windows Subsystem for Linux, now fully open source.
Mechatronics engineer turned product manager. I’m passionate about building tools that get out of the way and let people focus on what they’re trying to create. I’m lucky enough to spend my time building those things, talking to the people who use them, and occasionally sharing what we’ve learned on stage.

- Building the Windows Subsystem for Linux at Microsoft — now fully open source.
- Exploring how coding agents change the shape of developer tools.
- Lifting, playing guitar, and getting outdoors whenever the weather allows.

When I'm not working
Travelling
I love to travel and have lived in many different places. Most recently Konstanz, Germany, where I got to speak both German and French. Learning about new places and cultures is the fastest way I know to get a new perspective.
Building
I work on pet projects constantly. In 2014 I built a working quadcopter from scratch, programmed it, and learned to fly it. I have also built a hydrogen fuel cell powered RC car, and a robot that launches jelly beans into your mouth from across the room.
Training
The other way I push myself is physically, and outdoors. Lifting, climbing, and getting far enough from a screen that the only thing left to solve is the next hold.
