People correct AI translations before they publish them. A weekly job counts those corrections, lets gpt-oss-120b propose prompt rules within a fence, filters and tests them in plain code, and opens a pull request instead of changing the prompt itself. In a dry run the test rejected a sensible-sounding rule and passed another.

When Whizlabs and Tutorials Dojo hadn't caught up to the April 2026 AZ-400 exam update (hybrid CI/CD, GitOps with Flux v2 + ArgoCD), generating custom scenario questions with AI to fill the gap — including one where the AI itself got a nuanced hybrid setup wrong first.

Building the blue/green + feature-flag demo for AZ-400 practice: adding a user header, moving a feature from an env variable to an App Configuration flag — and the real debugging story, a 502 traced to GitHub Actions mangling a multi-line prompt.

Integrating SonarQube (via SonarCloud) into a GitHub Actions pipeline: the quirks that ate two hours (host-URL validation, version-specific scanner behavior, global-tool install issues), the fix (pinning an older SonarScanner for .NET), and how easy Dependabot + CodeQL were by comparison.

The build log for koorevaar.com itself: three evenings from buying the domain to a portfolio built with Aider+Qwen2.5, GitHub Actions pipelines, and a Terraform-deployed Azure Container Apps text-analysis demo behind a Cloudflare Worker + phi3:mini.
