Platform & Site Reliability Engineer | Cloud-Native | Kubernetes | Terraform | Go | Automation | CI\CD Pipelines


🧩 About Me

Navy veteran and Platform Engineer in Seattle building and running multi-cloud and hybrid infrastructure.
10+ years managing large-scale systemsβ€”from 5,000+ Linux servers to full Kubernetes and IaC deployments.
I build resilient platforms, automate relentlessly, and document everything for the next engineer.

β€œIf a process needs human intervention twice, it gets automated.”
