What I'm looking for

I seek roles where I can drive cloud-native reliability, GitOps adoption, automation, and cost optimization within collaborative, growth-oriented teams.

I am a Site Reliability and Cloud Engineer with hands-on experience designing, deploying, and operating cloud-native infrastructure using AWS, Kubernetes (EKS), Terraform, and GitOps practices. I have led migrations to ArgoCD and Helm, built CI/CD automation with GitHub Actions, and implemented cost optimization measures that saved significant cloud spend while improving reliability.

I thrive in high-demand environments across financial and e-commerce sectors, participating in on-call rotations, incident response, and observability improvements. I contribute to open source and community education, author technical content, and mentor cloud practitioners to foster knowledge sharing and stronger operational practices.
