About Quan
I am a dual CCIE (Enterprise Infrastructure & Security) with 12+ years designing, securing, and operating carrier-grade and enterprise networks across ISP, MSP, and financial services environments.
As Core Network Engineer at Brennan, I lead automation, IaC, and AIOps initiatives for the national backbone and customer estates. Highlights include architecting the GPT-powered NetAssist platform, industrialising Fortinet SD-WAN rollouts, and building PSIRT remediation tooling that blends telemetry, AI, and ServiceNow workflows.
Previously I supported the largest ANZ service providers as a Cisco Technical Consulting Engineer, led Oceania POP builds for China Unicom Global, kept Sydney's Opal Card transport network running at Cubic, and delivered advanced services with Juniper Networks. I thrive on bridging classic routing and security with modern automation, observability, and AI engineering.
