I build AI systems that ship — not demos, not prototypes. Production systems handling real traffic, built by someone who understands both the code and the chaos of operations.

I wrote SPARC — 3,000+ lines of prompt architecture that turns 12 specialized AI agents into a coherent development team. Security mandates, TDD workflows, human-in-the-loop review. It reduces scaffolding from 2 days to 4-6 hours.

From managing fast-food ops at 3AM to architecting LLM pipelines — that combination taught me what most AI engineers miss: the gap between "works on my machine" and "works under load at 2AM on a Saturday."
