I’m a Software Engineer specialized in Developer Tools. I work onMicrosoft Playwright, an end-to-end browser testing framework.

Previously, I worked atNetlify on all things developer-facing; built a job-queueing solution calledQuirrel (sold to Netlify); and received a Bachelors Degree in Computer Science fromHasso Plattner Institute near Berlin.

I’m the author of the popularSuperJSON library, was part of theReact 18 Working Group, and contributed to projects likeNext.js,Apache Traffic Server andPandas.

I write about my work atsimonknott.de.

Outside my profession, I enjoy woodworking, all kinds of design, cooking and cycling. I’m based in Berlin.Reach out if you want to have a coffee!
