Mark A. Baker


To integrate everything into the Web


Mark is an expert in, and a student of large scale distributed systems and software architecture in general. He has a special interest in Internet scale software and protocols, and in particular an in-depth understanding of the workings of the World Wide Web and the REST architectural style that inspired much of its design. He believes that, for the foreseeable future, the bulk of innovation in Internet scale systems will occur atop the Web.

He is best known as the leading proponent for REST style Web services which leverage the architectural characteristics of the Web itself for machine to machine communication and integration. He spent much of his own time during the previous decade, working within standards setting organizations in order to ensure that Web services specifications either took maximal advantage of the Web, or failing that, at least avoided being harmful to it.

Mark is also well known for his efforts to build out the Mobile Web through work in standards setting organizations, as well as through creating innovative mobile/wireless products at two startups, one of which he co-founded.
