About

Sofiane Z

Network architect focused on AI infrastructure.

I am a senior network engineer and CCIE #69931 with more than ten years of experience. My day-to-day background is latency-sensitive electronic trading infrastructure across multi-region data centers and public cloud, where determinism and tail latency are everything.

That same discipline is what AI fabrics demand: thousands of GPUs moving in lockstep, where one slow link stalls an entire training job. NetworkFactory is where I share what I learn about building those networks, through articles, labs and the book Building the AI Factory.
