Andrew is a pleasure to work with, and a true professional and great teammate. I joined a team late in the development cycle, having to ramp up quickly. Andrew offered clear, expert answers to my questions, quickly establishing himself as a go-to person on my list. Andrew's patience, guidance, and review of proposed changes were invaluable, improving the end product considerably. Andrew's knowledge of development tools and technologies is broad and deep. It would be a privilege to work with Andrew again. Hire him.
