About

A bit more context

Got into this the way most people do: curiosity about how things break, followed by a rabbit hole I never really climbed back out of. Most of my time goes into TryHackMe and Hack The Box rooms, home-lab builds, and picking apart other people's write-ups to see how they think through a box.

Not chasing a title yet - chasing reps. Right now that means going deeper on Active Directory attack paths and working toward the next certification on the list.
