Principal SRE | Writing about Kubernetes, Observability & Reliability Engineering from 11 Years in the Trenches

Principal Platform Engineering and DevOps Leader with 11+ years of experience building and operating high-availability cloud-native systems at enterprise scale. Currently leading SRE practices at ABB India, managing reliability for 25+ product modules across distributed global architectures. I write about real-world Kubernetes (AKS), Observability (Prometheus, Grafana, Loki), SLOs & Error Budgets, CI/CD, GitOps, and AIOps — lessons learned from actual production systems, not textbooks.
