Message

At Charter Radiology, I coordinate platform modernization and clinical system integrations across three radiology centers, including RIS and PACS migrations, infrastructure upgrades, and vendor delivery. I serve as executive sponsor and technical delivery lead for integrations, coordinating operational readiness and release sequencing.

At the US Office of Personnel Management, I managed federal technical delivery for IBM z/OS operations and enterprise support, leading cross-functional teams and maintaining program governance. I also managed security and modernization work, including the Mainframe PIV / CBA Project and recurring disaster recovery site-switch events.

At the US Food and Drug Administration, I managed DevSecOps platform delivery and CI/CD pipeline readiness, including Azure integration and FedRAMP authorization work. Earlier, I managed enterprise deployment automation with Puppet Enterprise and technical integration projects, drawing on experience across federal IT modernization, infrastructure, and enterprise systems.
