01 — about
I approach security the way I approach a network diagram: methodically, from the edges in. I'm drawn to the quiet, unglamorous parts of the work — mapping an attack surface, tracing a digital footprint, hardening a VLAN boundary — because that's where the real risk usually hides. I'd rather spend three hours verifying one finding than publish ten unverified ones. Continuous learning isn't a slogan for me; it's the daily baseline — new CVEs, new OSINT tooling, new ways enterprise networks get misconfigured.
