Cloud & DevOps
Engineer

I work with cloud infrastructure and DevOps tooling on AWS,
turning infrastructure and deployment processes into clean,
automated systems.

About Me

I work with cloud infrastructure and DevOps tools, mainly in the AWS ecosystem. I enjoy designing systems that are automated, secure, and easy to operate.

This portfolio site presents hands-on projects where I use Terraform, Docker, and Kubernetes to provision infrastructure, deploy applications to EKS, automate delivery with GitHub Actions, and add monitoring and alerting using Prometheus and Grafana.

Portfolio Projects

Selected projects demonstrating infrastructure automation, CI/CD pipelines, Kubernetes deployments, and observability on AWS.

AWS Portfolio Platform (IaC + Remote State)

A secure AWS portfolio platform deployed end-to-end with Terraform. Includes a VPC-based setup, least-privilege IAM roles, a serverless visitor counter (API Gateway + Lambda + DynamoDB), and Terraform remote state in S3 with locking. Built to be repeatable, version-controlled, and easy to redeploy.

Technologies Used:

AWS Terraform S3 Remote State VPC EC2 IAM Lambda API Gateway DynamoDB

EKS CI/CD (GitHub Actions + OIDC)


Containerized web application deployed on AWS EKS with a GitHub Actions pipeline. The pipeline builds and pushes the Docker image to ECR automatically, then performs a gated deployment to EKS. Authentication uses AWS IAM OIDC.

Technologies Used:

Docker AWS EKS Kubernetes AWS ECR GitHub Actions OIDC

Observability on EKS (Prometheus + Grafana)

Monitoring and alerting added to the EKS workload from Project 2. Installed kube-prometheus-stack with Helm, visualized cluster and workload metrics in Grafana, and created a custom PrometheusRule alert. Alert lifecycle was validated (inactive, pending, firing) and documented with screenshots.

Technologies Used:

Helm Prometheus Grafana Alerting AWS EKS Kubernetes
