Professional Experience

Cornell University — Lab of Ornithology | Senior Lead Infrastructure Administrator March 2026 – Present

We had three on-premises vCenters managing multiple VMware clusters and ESXi hosts. Due to increasing VMware licensing and infrastructure costs, we evaluated Azure Local as the target platform. I assessed VM utilization and application dependencies, designed the Azure Local clusters, and mapped VMware VLANs and port groups to Azure Local logical networks. We used Azure Migrate source and target appliances for discovery, replication and migration. During scheduled weekend windows, we performed final synchronization, shut down the source VMs, brought up the Azure Local VMs and validated networking, applications, monitoring and Rubrik backups. We migrated the workloads in phases and retained the VMware VMs temporarily for rollback before decommissioning the ESXi resources.
