I'm an independent full time open source developer.
I work on projects in the TypeScript ecosystem, most notably typescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code. I'm also the author of O'Reilly's Learning TypeScript book, a Microsoft MVP for developer technologies, and an active conference speaker.
My personal projects range from static analysis to meta-languages to recreating retro games in the browser. Also cats. 🐱
Because I'm independent, I rely on sponsors to fund my work. They deserve our sincere appreciation and gratitude.
