Mat “Wilto” Marquis is a developer at Filament Group, where he helps create usable and highly-accessible websites for a wide range of clients — including the recent BostonGlobe.com.

Mat is a member of the jQuery Mobile team, technical editor and author for A List Apart, and Chair of the Responsive Images Community Group. He contributed several chapters to the fourth edition of Learning Web Design, and is an active member of the open source community. Mat has beaten Mega Man II for the NES — on “difficult” — without losing a single life. He's probably flipping out about something on Twitter as we speak.
