Where AI meets
the fabric.
No fluff.

A practitioner's perspective on AI infrastructure networking — DC fabric design, RoCE/RDMA, GPU clusters, and the technologies reshaping how data centers are built.

About

Building the networks that run AI.

I'm Mario Geovanny Campos, a Senior Network Engineer and CCIE Enterprise Infrastructure #67478 with deep experience designing and operating complex network infrastructures across enterprise, service provider, and data center environments.

My background includes white-box DC networking with VXLAN overlay fabrics on disaggregated hardware, enterprise campus design with Cisco SDA, and service provider routing. That foundation is now pointed squarely at AI infrastructure.

I'm currently pursuing the CCDE with the AI Infrastructure elective — one of the most demanding design certifications in networking — while building hands-on lab experience across Cisco, Arista, Juniper, and SONiC.

FluxFabric is where I document the design decisions, the tradeoffs, and the deep dives. Written for engineers, by an engineer.
