John Brunelle

Systems and Network Architect

I’m a systems and network architect with 40+ years of experience designing enterprise infrastructure, from VoIP and carrier-class networks to security architecture and large-scale systems engineering.

I currently work at Cisco Systems, where I help financial and retail customers design solutions that actually hold up in production.

Over four decades I’ve built things at Digital Equipment Corporation, BBN/Genuity/Level 3, Smith and Nephew, and Cisco. Network operations centers, VoIP platforms carrying real traffic, data centers, security frameworks. The kind of infrastructure people only notice when it breaks, which is the point.
