Who I Am

Building AI-Powered Systems That Work

I architect and build AI-powered systems for companies that need them to actually work. With 10+ years building production web applications, I've focused on making LLMs useful in production — building the full stack from database design to API architecture to React frontends to AI agent systems.

Technical Architecture

System design from database to API to frontend. I architect the system properly, build it, and deploy it — or guide your team through implementation.
