Off the clock

The human part

Greater Orlando based. I taught open-water sailing before I ever touched a SIEM, and I still do my best thinking within sight of salt water.

Coffee

Black, early, non-negotiable.

Off hours

Homelab tinkering, CyberWarfare Labs challenges, and finishing a WGU degree at night. Graduation is close enough to taste.
