Notes on enterprise AI governance, portfolio architecture, and the practical work of delivering secure digital services in the public sector.

  1. Fifty-five hours: a public registry built specification first

    I took a public-facing registry from scratch to production in about 55 hours of development time. The specification carried most of the load, and a person approved every handoff.

  2. From specification to evidence: how AEGIS keeps a person in charge

    AEGIS is my open-source toolkit for delivery with AI agents. It writes the specification first, blocks code until the specification is complete, and records the person who approves the release.

  3. Model Context Protocol as an architecture knowledge system

    Architecture standards fail at the moment of the decision. MCP moves them to where the decision is made.

  4. Six weeks, one mandate: architecture decisions when the date is not negotiable

    A fixed launch date does not change what good architecture is. It changes which decisions you are allowed to defer.

  5. What it takes to put AI inside a government delivery pipeline

    Most AI pilots in the public sector fail at the governance seam. The work is in making governance something a delivery team can program against.
