About Me

DevOps & Cloud Engineer with hands-on experience building and automating cloud infrastructure using AWS, Kubernetes, Terraform, and CI/CD pipelines.

I have deployed production-style applications on AWS EKS, automated delivery with GitHub Actions, and built monitoring solutions with Prometheus and Grafana to improve visibility, reliability, and deployment consistency.

My focus is on scalable infrastructure, reliable releases, observability, and cloud operations, supported by a practical background in troubleshooting and systems support.

Open to: DevOps Engineer, Cloud Engineer, IT Operations, Infrastructure, and Platform Support roles in EU and Germany (open to relocation).

Featured DevOps Projects

A focused selection of DevOps and cloud projects covering Kubernetes, CI/CD, infrastructure automation, observability, and production-style deployments on AWS.

SaaS microservices platform on AWS EKS architecture

SaaS Microservices Platform on AWS EKS

Built and deployed a production-style microservices platform on AWS EKS using Terraform, Kubernetes, Docker, and GitHub Actions. The platform includes 4 services (auth, tenant, task, gateway) with PostgreSQL, external access through an AWS LoadBalancer, and persistent storage backed by EBS.

  • Automated delivery with GitHub Actions, reducing deployment time from ~2 hours to ~2 minutes.
  • Improved reliability by resolving pod scheduling, storage, and service communication issues in a live EKS environment.
