Hi, I’m Christoph. For over 25 years I’ve been building open source tools that shape how millions of developers work, including projects I created like Jest, Metro, Yarn and jscodeshift. I previously led JavaScript Infrastructure and managed the React Native team at Facebook in Menlo Park and London.
Today, I work as an Engineering Director at Cloudflare and as CEO of Nakazawa Tech in Tokyo. Recently, I’ve been building:
- Athena Crisis — an open source turn-based strategy game
- fate — a modern data client for React
- fbtee — the JavaScript & React Internationalization Framework
- Codiff — a fast diff viewer with walkthroughs
- ReMDX — beautiful Minimalist React & MDX Presentations
- and way more…
I write about Frontend Development, Engineering Management, Leadership, and User Experience.
Open source has shaped my journey since I first published a project in 2006 and joined GitHub in June 2008. If you want to support this work, please consider a GitHub sponsorship.
