About

Twenty years in IT and security. Director of Information Security at a large financial services firm, managing security engineering and identity teams. At night, I build things: autonomous AI agents, local inference infrastructure, apps that make my own life run better. I've been doing both long enough to know they're the same skill — understanding systems deeply enough to make them do what you want.
