Software Development Engineer 2 at Microsoft who delivered Kubernetes fleet changes and $4M annual savings.

At Microsoft, I led a three-member team in migrating more than 4,000 clusters from Intel-based SKUs to lower-cost Flex SKUs, realizing $4–5M in annual savings.

I also created cost insights dashboards for Azure and AWS Kubernetes Runtime spend. They helped identify inefficient clusters and workloads; decommissioning over 40 idle clusters and right-sizing others achieved $4M in annual savings.

For Kubernetes Runtime, I architected and delivered Fleet Groups, consolidating workloads onto a self-scaling pool of AKS clusters with dispatch based on cluster health, pod capacity, and queue depth.

Previously, at Goldman Sachs, I led work on commercial real estate collateral data flows and client-side field-level encryption. At Oracle, I developed and maintained backend and UI components for the division-wide REMO tool.
