Message

At Calix, I lead the DevOps and platform engineering function across AWS and GCP, managing a distributed team of 12+ engineers. I defined a shared Terraform standard and standardized application delivery with ArgoCD and GitOps.

I own production reliability across US and Canada environments, including SLOs, observability, incident response, and cloud cost optimization. I also use AI tools in daily engineering work to support IaC authoring, troubleshooting, and documentation.
