Platform Guy at Valka.ai — clouds, infrastructure, automation, cost optimization, security & more

About

I'm a Cloud & Platform Engineer with over a decade of hands-on AWS experience, plus working knowledge of GCP and Azure. I like sitting at the intersection of business, product and engineering — turning infrastructure into something teams can build on safely and quickly, whether that's a customer-facing product or an internal platform.

Along the way that's meant designing landing zones and Kubernetes platforms, writing the Terraform and Ansible that keeps them reproducible, chasing down unnecessary cloud spend, and helping teams pick up better DevOps habits.
