Brendan Battersby
Network Architect
Resilient enterprise networks designed for security, scale, and business continuity
9 years in enterprise routing, security & cloud
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 2500+ 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.
