grep summary cv.txt

I came to AI through 20 years of building systems that have to work: mechanical engineering, ISO 9001 quality management, experimental research. That discipline carries directly—design for failure modes, not happy paths.

Today I build production AI: zero-cloud document pipelines, multi-agent LLM platforms with persistent RAG memory, and developer tooling that ships with real test coverage and documentation. I also teach—12 of 15 engineers I've mentored secured AI/ML roles within 6 months. I built hebikata to formalize that curriculum as open-source tooling.
