I lead enterprise technology transformation across cloud, networking, infrastructure, and service-oriented operating models.

Message

I'm currently a Senior Manager of Systems Engineering at Nutanix, following systems engineering leadership roles at Fortinet. I lead complex technology transformations spanning cloud, networking, infrastructure, and organizational operating models.

At NI, I established an enterprise architecture practice, created an IT emerging-technology innovation program, and led a shift to service- and value-chain-oriented IT. Over 18 years, I've built and managed global engineering teams, delivered network and cloud architectures, and mentored technical leaders across Kubernetes, Terraform, DevOps, ITIL4, SRE, and enterprise architecture.
