I'm a fractional CTO that helps mission-driven organizations simplify complex digital infrastructure. Over the past 14+ years, I’ve led high-impact projects for teams like the City of Boston, MTA, County of Marin, and Berklee, working across Drupal, Rails, and React. I’ve architected everything from GTFS-integrated transit tools to accessible design systems to zero-downtime deployment pipelines. My focus: building resilient systems with limited complexity. I believe in good code, good people, and good ribs. On weekends, you'll usually find me tending to a smoker, not a server.
