CTO at JHFit · Product Engineering Lead
I build and operate products across web, mobile, backend, and cloud, turning customer needs into working software and reliable business workflows.

I build AI development harnesses and business ontologies that connect business rules, code, and tests. My focus is making AI-assisted work verifiable, from product data extraction to regression checks.
