    "summary": "Hey, I'm Renato, but most people know me as Tim. Senior DevOps Engineer with 8+ years building and scaling cloud platforms for e-commerce, fintech, pharma and logistics. 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.",
