About

Engineer first, always moving

I'm a husband and father of a young family, and an engineer who cares about systems that are simple to run and honest about what they cost. Clients get a single senior point of contact who can reason about the product, the code and the infrastructure together.

Away from the keyboard, the court, the gym and the trail keep me sharp. They also shape how I work: consistency over heroics, form over ego, and patience on the long climb.

  • BasketballTeamwork and reading the play.
  • GymProgressive overload, applied to code.
  • Hiking & natureOne step at a time, eyes on the summit.
  • Family & travelThe highest priority, and the best perspective.
