> Consultant, trainer, and speaker on software delivery, platform engineering, Kubernetes, GitOps, and AI in engineering.

Simon Koudijs is a consultant, trainer, and speaker based in Amersfoort, Netherlands,
trading as Koudijs IT (KvK 97788708). The work spans software delivery, engineering
workflows and CI/CD, platform engineering, Kubernetes, GitOps, and the practical use of
AI in engineering — with a bias towards what teams can actually apply over what sounds
impressive. He is also the founder of ConfigButler (https://configbutler.ai) and the
