GE Digital: cutting $14M of cloud cost

From May 2022 to February 2024 I was Cloud Development Manager at GE Digital in San Ramon. The organization built software and industrial IoT energy services for commercial turbine operators.

I directed the strategy and wrote code for an infrastructure-as-code cloud serving thousands of services. I led the migration of EC2 services and workflows to Kubernetes.

The numbers:

• $14M reduction in cloud service provider costs, while improving performance and customer relations.
• A contribution to $70M of operating cost avoidance over 2 years.

The rest of the job was operations. I rebuilt how we ran them, with a focus on pipelining features and learning from root cause analysis. I worked closely with the Splunk monitoring and security teams to get ahead of events that would affect our service levels. When the cyber security teams were understaffed, I advised them and operated as DevSecOps.

The technical ground was AWS load balancers and API gateways, Terraform, Helm, Kubernetes and Splunk APM.
