Hi, I'm Josh!
I'm an 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 a frontend developer at Sentry.
Thanks to my Sponsors
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.
| Platinum Sponsors (>=$100/mo) | Gold Sponsors (>=$25/mo) | Silver Sponsors (>=$10/mo) | Bronze Sponsors (>=$5/mo) |
|---|---|---|---|
Now, all my sponsorships are directly forwarded as monthly funds to Flint.
