JC Marin is an AI infrastructure engineer who builds AI systems in the one kind of environment where "move fast and break things" is not on the menu: high-security enterprise networks where every deployment must answer for where the data goes.

As an AI subject matter expert at a major aerospace and defense company, he architected a multi-agent AI platform for an air-gapped classified network, including large-model serving, request routing, and per-user vector memory. The questions this book treats as drama, citations, provenance, superseded documents, and data that never leaves the building, are the questions he answers professionally.

He also runs an independent AI solutions practice and operates a self-hosted multi-GPU inference environment serving open-weight models, the same build-it-yourself-first philosophy this series teaches. He is based in Melbourne, Florida. Building AI That Knows Your Data is his first technical book series.
