// Summary

People first. Good systems augment good people. I bring 30 years of IT experience to dependable technology for small businesses, executives, and complex organizations. My work spans enterprise support, cybersecurity, knowledge and records migrations, and developmental AI governance through GKOS and GKOS-Engine. I am also conducting independent research into a specific aspect of gravitational physics.

    Governed agent tooling

    10 read-only MCP tools

    Leads the design and development of GKOS-Engine and related knowledge tools, using AI coding agents to help with implementation. I set requirements, review changes, test behavior, and decide what ships. The tools emphasize provenance, deterministic validation, reproducible context, and bounded agent access to support human judgment.
