I run 10+ production Kubernetes clusters on AWS, GCP, Azure, and air-gapped bare metal.
I'm the sole operator, from control-plane bootstrap through storage and the incidents. AWS Certified Solutions Architect. When something breaks, I write up what it actually turned out to be.
About
I like the problems where the alert is pointing at the wrong thing. A KubeAPIErrorBudgetBurn that was really a seven-year-old SSD. A control plane that was really out of etcd quota. Most of what I know came from chasing those down and then writing them up.
That is also what pulled me toward observability. In every one of those cases the fix was straightforward once the data finally said what was actually wrong, and getting to that point took far longer than it should have.
Selected work
-
Traced an error-budget-burn alert to a dying disk
KubeAPIErrorBudgetBurn on a production control plane, availability down to 90.9%. It was not load and it was not the network. smartctl found a seven-year-old SSD failing underneath etcd fsync latency. Swapped it live.

Bootstrapped highly available Kubernetes on bare metal
Ansible and kubeadm from scratch, with HAProxy and Keepalived holding a virtual IP in front of the API servers. Failover validated by pulling nodes on Proxmox.
-
Moved production from on-premise to AWS EKS
Migrated live workloads, added Karpenter for autoscaling, then spent the following weeks cutting the bill back down.
