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.

As an independent consultant, Mat’s goal is to ensure that meaningful, well-structured content can reach users in any browsing context—regardless of the size of their screen, the speed of their internet connection, age of their device, or the combination of browsers and assistive technologies they use to experience the web.
