Summary
👤
Senior🎓
Top SchoolJeremy Mcminis is a Principal Engineer and seasoned AI/data engineering leader with 19 years of experience building production-grade systems across startups and enterprise environments. Based in Ann Arbor, he combines hands-on engineering—shipping LLM-powered applications, RAG systems, and scalable data platforms—with strategic technical leadership as a founder, fractional CTO, and principal R&D engineer. He has a track record of designing data warehouses, ML platforms, and human-in-the-loop workflows that move AI from prototype to revenue-generating product while minimizing technical debt. An active open-source contributor, he’s implemented core features for high-performance scientific software (QMCPACK) and improved developer-facing integrations in widely used tooling like Rasa. Comfortable from low-level algorithm tweaks to board-level architecture, he blends a physicist’s rigor (PhD, UIUC) with a pragmatic taste for simple, obviously correct solutions. Outside work he’s equally drawn to coffee, data, and startups—often turning experimental ideas into practical products.
