David Williams is a Advisor at Prodeitious. Colleagues describe him as "David has immense talents that he brings to the office every day. A bit of a rebel, David will hold strong to his ideas and he is usually right. At Coupa, David was the champion for us to choose Ruby on Rails as our development framework when it was practically unheard of in the enterprise space (early '06). As our lead engineer from Day 1, he is credited with building so many pieces of the Coupa product. 6 years later, he still is coding while overseeing the architecture, scalability and security aspects of the solution."
