Platform and DevOps engineer with nearly 20 years across bare-metal, HPC, and cloud-native production systems. I build secure, resilient platforms on Kubernetes, GitOps, and the Cloud Native stack, and I lead teams to ship.
- Focus: Kubernetes, GitOps, platform engineering, SRE
- Stack: AWS, GCP, Terraform, Helm, ArgoCD, Flux, Istio, CI/CD, Go, Python, Bash
- Blog: https://teerakarna.github.io
- gitops-demo: a GitOps system. Terraform (kind + ArgoCD), dev/preprod/prod, and ephemeral per-PR environments.
- service-demo: a Go API with a distroless image, a Helm chart, and a full CI/CD pipeline.
- openclaw-journey: Terraform and Ansible to deploy on a hardened Debian VM.
Each demo runs locally and is written up on the blog, so you can follow along.
