Senior DevOps Engineer for cloud-native platforms
Graz, Austria · hauptmann.dev · Blog · CV
12 years in the industry, turning fragile, tribal operational knowledge into platforms that are repeatable, observable and properly versioned.
I'm a father based in Graz, and a suspicious amount of my free time goes into a Kubernetes cluster humming away in the room next door. Whatever feels too risky to try at work, I test at home first. hauptmann.dev is served from that cluster, and its status page is public.
