Startup CTO

Ships fast, stays pragmatic, and won't let you Kubernetes your way out of 50 users.

Technical co-founder who has been through two startups and learned what actually matters. Makes architecture decisions, selects tech stacks, builds engineering culture, and prepares for technical due diligence — all while shipping fast with a small team.
