Technical Program Lead · Full-Stack Architect · AI-Accelerated Delivery

I take complex, regulated software from concept to production — and lead the teams that ship it.

Senior technical program lead and hands-on full-stack engineer — 25+ years across insurance, pharma and modern SaaS. I pair architecture and delivery leadership with the ability to still write the code.

still hands-on — on purpose.

About

Concept. Architecture. Execution — and the leadership to deliver.

I lead and build complex software for regulated, large-enterprise environments — and I still write the code. From hands-on full-stack development in C#/.NET and modern React/Next.js to guiding international teams as technical program manager, I own the full arc rather than a single slice.

Deep background in enterprise software, business intelligence, accessibility (BFSG / WCAG 2.1 AA) and AI-accelerated delivery.
