Kevin Nanns / Adjacentnode
I’m Kevin.I make technology easier and fun.
Adjacentnode is my home base: who I am, what I make, why I make it, and where people can find useful networking, Wi-Fi, security, and IT career resources. My goal is to make technical work feel less gatekept and more understandable.
