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.

Let's figure out how technology works.

Real gear, packet captures and controlled tests, explained so anyone can follow along. Change one setting, see what happens, and learn why it happened.
