Career Highlights
|
I have delivered dozens of projects in leadership and contributing roles. With a pragmatic style, I have found repeated success by focusing on the development of clear and simple interfaces to solid frameworks and foundational systems. I emphasize loosely coupled modules, abstraction, and flexibility, in highly maintainable systems.
