About

Engineering Cloud Solutions

I'm a DevOps Engineer with 5 years of experience designing and automating cloud infrastructure on AWS. I specialize in Kubernetes, Terraform, and CI/CD pipelines, with a strong focus on infrastructure as code and cost optimization.

I've delivered solutions across retail, healthcare, and IoT industries, from optimizing GitLab CI/CD pipelines to migrating healthcare EMR systems to Kubernetes with 99.9% uptime.

Beyond engineering, I share knowledge through technical writing and help fellow engineers level up their DevOps skills.
