Jon DeVaan is currently the senior vice president for Windows Development at Microsoft.

He started at Microsoft in 1984 working on application programs for the Macintosh and was an original programmer on Excel 1.0. DeVaan played an important role in defining the engineering practices of Microsoft in the early days of writing GUI software. In this time line DeVaan shipped Excel 1.0 through Excel '95 on Macintosh, OS/2 and Windows platforms and was one of the leaders who drove the evolution of the Microsoft applications division from fiercely independent standalone teams to an integrated team creating Microsoft Office through the delivery of Office '97 and the design of Office 2000. In 1999 he left the Office group to work on the online and TV areas of Microsoft participating in the development and launch of UltimateTV(r) and the Microsoft TV(r) platform. In 2002 DeVaan led a company wide effort to revitalize the engineering practices of Microsoft working for Bill Gates. In 2006, he assumed leadership of the Windows Core Operating System Division (COSD), responsible for the teams that create the core components and architecture of Microsoft Windows, with the mission of revitalizing the team's software engineering practices.
