I am Alperen. I make networks up and running for a living. I have been on the operating, building, designing and selling sides of that world. These days my focus is the fabrics behind AI and GPU clusters.
This blog is my engineering notebook: lab builds, configs and protocol deep dives, tested before they get published. On the side I build FabricForge, a DC fabric designer.
