Kubestronaut: all five CNCF Kubernetes certifications (CKA, CKAD, CKS, KCNA, KCSA). I've cut deployment time by up to 70% with CI/CD and GitOps, saved real money with FinOps, and moved entire Kubernetes platforms across clouds with barely any downtime. And I truly believe great infrastructure starts with people: transparency, blameless culture and staying calm when things catch fire.",
