About Me

I architect and deliver enterprise networks across retail, manufacturing, and finance environments. My recent work includes leading an eBGP/OSPF architecture redesign, designing redundant hybrid cloud connectivity to Azure with VeloCloud NVAs, and governing zero trust policy across 2,500+ endpoints with Zscaler. I prioritize designs that are resilient and clearly documented.

When I'm not at the whiteboard, you'll find me lifting, hiking, or playing DnD.

Network Architecture & Design

Each portfolio design combines patterns from my enterprise experience with representative constraints created to demonstrate my architecture process. These are original reference designs, not replicas of any single production environment.
