John deVadoss

John deVadoss leads the Patterns & Practices team at Microsoft. His responsibilities include platform and architecture strategy for the developer tools and the application platform. He has over 15 years of experience in the software industry; he has been at Microsoft for over 10 years, all of it in the enterprise space – as a consultant, as a program manager in the distributed applications platform division, as an architect working with some of Microsoft’s key partners, director of architecture strategy and most recently leading technical strategy for the application platform.

Prior to Microsoft he spent many years as a technology consultant in the financial services industry in Silicon Valley. His areas of interest are broadly in distributed application architectures, data and metadata, systems management and currently on edge architectures (both services and access), but most of all in creating business value from technology investments.

John has a BE in Computer Engineering, and an MS in Computer Science from the University of Massachusetts at Amherst, where he also did graduate work towards a PhD in Computer Science - which he hopes to complete at some point in the future.
