Location: Cupertino, California, United States
Profile: https://flows.cv/davidhoa

Software Professional with 15+ years of web-scale and enterprise level programming experience, in permanent beta. Because of my experience designing complex systems (Web Service Infrastructure, Query Optimizer) where every change could have critical impact outside the scope of the immediate problem, I can make strategic and careful decisions at the speed needed for timely product development. I'm experienced leading up to 20 engineers (direct and indirect) as part of high performing teams, and enjoy helping my folks develop their skills and progress in their career.
