About me

I am a DevOps Engineer with a software development background, specializing in Kubernetes, GitOps, and infrastructure as code. I help teams migrate to Kubernetes, automate infrastructure and deployments using Terraform and ArgoCD, and optimize cloud costs through right-sizing and autoscaling. I also build production tooling in Python and Go to deliver custom automation solutions.
