Jasen Carroll

ASQ Certified Software Quality Engineer. I do quality and validation for FDA-regulated device and pharma software, where the evidence a reviewer can actually follow is the deliverable - not the paperwork around it. I also build developer tooling, classical ML, and RAG systems.

I built an AI assistant that can't phone home

Five local data sources, zero network egress, and the bugs that only show up when you run it.

I passed the CSQE. The certificate is a signed JSON file.

A publicly queryable AI assistant over a SaMD QMS, RAG architecture. Demonstration only - built on a synthetic QMS not authored by me.

How pyr Works

A look under the hood at a tool that manages Python without being Python.
