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.
docker build portfolio-frontend:$BUILD_NUMBER
aws ecr get-login-password | docker login
docker push portfolio-frontend:$BUILD_NUMBER
kubectl apply namespace/deployment/service/ingress
kubectl rollout status deployment/portfolio-frontend
Cloud, automation and operations
Cloud & Infrastructure
AWS EC2, ECR, IAM, Security Groups, Route/DNS, Elastic IP, Azure exposure and production environment support.
Infrastructure as Code

Kubernetes & Containers
Docker image builds, k3s deployments, services, imagePullSecrets, Traefik ingress and rollout troubleshooting.
CI/CD
Jenkins pipelines with credentials, secure deployment, build numbers as image tags and controlled rollout checks.
Observability & SRE
Incident-focused monitoring mindset with CloudWatch, Prometheus, Grafana, logs and runbook-driven operations.
Security
Least-privilege IAM, private ECR, SSH restriction, HTTPS, certificate management and secret handling practices.
