About
I'm a Senior DevOps / SRE Engineer, working remotely from Brazil. I look after Kubernetes platforms and the AWS and Azure infrastructure around them, for several client environments at the same time. That shapes the problems I get: isolation, cost, and keeping upgrades boring.
What I work with
Kubernetes, Karpenter, Argo CD, Terraform, Prometheus, Grafana, Thanos/Mimir, Loki, OpenTelemetry and External Secrets Operator, on AWS and Azure. CKA, CKAD, KCSA and KCNA.
Why this blog exists
Most Kubernetes writing comes from teams running one cluster, in one cloud, for one product. Running many clusters for many clients is a different job, and it is badly documented. I write the parts I could not find when I needed them.
Everything published here is reproduced outside client environments before it goes up. No client names, no internal identifiers.
