Writing JS, CSS, and HTML professionally since 2004. Open source contributor to projects like jQuery, jQueryUI, ESLint, Webpack, npm, JSCS, Esprima and more. I’ve also served on the CSSWG on the CSSOM spec and on the jQuery Foundation Board of Directors (now the JS Foundation). I enjoy developer tooling, performance optimization, and software craftsmanship. When I’m not programming or teaching, I enjoy spending time with my wife and twin sons, playing video games, and obsessing over boutique salt varieties.
