Summary
Cas Lubbers is a Senior Software Engineer based in Arnhem with 10 years of experience building cloud-native, containerized systems and developer tooling. He combines deep hands-on expertise in Kubernetes, Docker, CI/CD and observability with backend skills in Java, Kotlin and Go, and a practical grounding in PostgreSQL, Ceph and Kafka. Certified as a Kubernetes Administrator in 2022, Cas has helped ship production platforms and tooling at companies like Avisi, Red Kubes (Otomi), and Akamai, bridging platform engineering and developer experience.
