Open Source

I was on the core Babel team for a short amount of time before joining Facebook. I mostly improved Babel/Babylon's parsing of Flow types, enabling a richer set of ESLint plugins to be created for Flow syntax.

Below are some other projects I've either built or maintained. Nothing very recent, though.

See more on GitHub.


PHP implementation of IBM’s specification for representing JSON as XML - developed to add drop-in support for XML to existing JSON APIs through a HTTP middleware.


Built much of, and maintained, a plugin providing lint & auto-fixing support for Flow type annotations in ESLint.


Team of idiots. Building stupid stuff at the PubHack hackathons.

Blog
