About

I'm a full-stack engineer who owns the whole thing: architecture, LLM orchestration, evaluation loops, telemetry, and the cost-and-latency tradeoffs that keep AI reliable once real users show up. Most of what I've built, I've built solo, top to bottom.

I've worked across medical data, dealership finance, marketing, and developer tooling. I care about correctness. I've paired LLMs with deterministic math engines when the numbers had to be exactly right. And I care about catching failures before users do, with real test coverage instead of hope.

Selected Work

AI revenue optimization for auto dealerships

Heavy financial-data platform on AWS. Parses raw and scanned dealership financial statements, pairs a fine-tuned LLM with a deterministic math engine so numbers are always exact, and lets non-technical stakeholders query in plain English. ~90% plan-to-action time reduction.
