I'm a full time open source developer in the web development ecosystem.
I work on projects that help improve code quality, most notably typescript-eslint: a powerful static analysis toolset for JavaScript and TypeScript code. I'm also the author of O'Reilly's Learning TypeScript book, a Microsoft MVP for developer technologies, and an (upcoming) developer at Sentry.
I was an independent maintainer from 2022 through 2025. Nowadays I work on open source in my spare time. My work was and is supported by these wonderful sponsors. They deserve our sincere appreciation and gratitude.
