Building reliable cloud platforms that ship faster.

I’m Sarath Kumar Kizhakkethil, a Senior DevOps Engineer with 9 years of experience across AWS, Azure, Kubernetes, Terraform, CI/CD automation and observability. This portfolio is not just a website — it is deployed through a real DevOps pipeline.

How this website actually works

The portfolio is built to demonstrate the same skills used in production DevOps work: Infrastructure as Code, containerisation, private registry, Kubernetes deployment, ingress routing and HTTPS.

A deployable pipeline, not a static CV

Every meaningful UI change is packaged into a Docker image, pushed to ECR, and rolled out to Kubernetes through Jenkins.

🚀

Jenkins pipeline stages

Checkout → Docker build → ECR login → image push → ECR pull-secret refresh → k3s deployment → rollout verification.
