David is a serial entrepreneur who’s been building with Rails for 15+ years. As former CTO at Suppli, a fintech serving construction distributors, he shipped LLM features in production where accuracy and cost accountability aren’t optional. Now focused on Rails and AI full-time, he’s learned expensive lessons about observability, debugging, and treating AI infrastructure with the same engineering discipline as any other production dependency.
