Cloud Reliability Engineer at Mendix (Siemens)
I've been keeping cloud platforms running at Mendix for 5 years. Incident response, infrastructure hardening, and making sure deployments don't break things on a Friday evening.
At home I run the same stack because I want to: a 4-node Talos Linux Kubernetes cluster, fully GitOps'd with Argo CD, with observability, ingress hardening, and DNS automation. All self-built, all in Git.
I make production safer to change. Incident response, rollout design, observability that actually tells you something at 3 AM, and alerting that doesn't go off for nothing. Systems should be explainable under pressure, not just work when everything is fine.
Declarative everything. If it's not in Git, it didn't happen. Reproducible rollouts, clear ownership, and security that's part of the platform, not added afterwards. I use AI tooling where it actually helps (automating the boring parts, catching mistakes early), not as a buzzword.
