About

20+ years hardening and running Linux, z/Linux, and IBM mainframe infrastructure, most recently owning end-to-end security and modernization strategy for a production z/Linux fleet of 1,000+ RHEL/SUSE servers on IBM S/390X mainframes.

Built the Rosetta Stone legacy-modernization pipeline — first shown at Red Hat Summit, expanded at the 2026 Red Hat Conference in Atlanta — and Web3270, an open-source, browser-based TN3270 client with a built-in mainframe security-testing toolkit. Author of eight books on private, auditable AI infrastructure.
