About Kevin

I'm Kevin.

I'm a network architect. You might know me as @adjacentnode.

I taught for four years before I ever touched a network, then took a NOC job in 2012 I wasn't ready for. Now I show you what your own Wi-Fi and devices are really doing, and help more people find their way into networking.
