About

I'm a Senior Cloud / DevOps Engineer with 15+ years building, automating, and securing distributed platforms for regulated enterprises. These days I move on-prem Hadoop and Spark workloads onto serverless AWS, run production Kubernetes with zero-downtime deploys, and manage it all as Terraform code shipped through GitHub Actions. It rests on deep operational roots — scaling 120-node Hadoop clusters, hardening Kafka and ClickHouse — the same least-privilege discipline I now bring to cloud IAM and Kubernetes RBAC.
