The Iceman. David's parents met at IBM and he's been using (and breaking) computers since before he could walk. After studying computer science at TJHSST and Duke University, he's been at Viget since 2008, where he leads technical engagements with some of our biggest clients.
David strives to deliver high quality, forward-thinking software on time and budget. His primary interests include database design, functional programming, distributed architectures, and being right almost exclusively.
