  1. GitLab CI for Kubernetes: a blueprint library for many apps and many clusters

    A delivery architecture that survived several apps, two rings and more than one cluster: a versioned blueprint library, thin app pipelines, a fleet repository that is the only thing talking to Kubernetes, and a live ring that releases what preview already ran instead of building again.

  2. When is an AI agent's work done?

    An agent opens a pull request in twenty minutes; a person takes an hour to review it. DOP's answer: no green, no PR — and green has to be earned on a commit, not a dirty tree.

IT product development

From the first specification to a shipped product: architecture, the team, and the operating cadence that makes delivery predictable instead of heroic.
