I'm an independent full time open source developer.

I work on projects in the TypeScript ecosystem, most notablytypescript-eslint: the tooling that enables ESLint and Prettier to run on TypeScript code.I'm also the author of O'Reilly'sLearning 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.

Platinum Sponsors (>=$100/mo)	Gold Sponsors (>=$25/mo)	Silver Sponsors (>=$10/mo)	Bronze Sponsors (>=$5/mo)
