Mat has kept busy pretty during his decade and a half of working on the web: from a member of the jQuery Team, to an editor of the HTML specification, to a speaker at conferences like An Event Apart and Smashing, to two-time author for A Book Apart and Google’s web.dev on the topics of images and JavaScript.
