// about
Who I Am
I'm a DevOps engineer based in Uithuizermeeden, Netherlands, with a strong track record in cloud-native infrastructure, platform engineering, and application modernization. I specialize in making complex systems reliable, automated, and production-ready.
At DUO, I've worked across three teams — migrating legacy monoliths to microservices, guiding teams through cloud migrations, and running the Linux and OpenShift platform that the entire organization depends on. Through my own company Automatrix, I help clients improve their cloud infrastructure and achieve compliance goals.
I hold both the CKA and CKAD certifications and have a deep passion for Kubernetes — from production OpenShift clusters at work to the RKE2 cluster running in my homelab.
When I'm not in the terminal, I'm usually doing renovation work on my house — the same engineering mindset, different tools.
