About

I'm a networking and cybersecurity professional who works across both sides of the fence — finding weaknesses as an attacker, and closing them as a defender. My day-to-day spans penetration testing, SOC monitoring & incident response, red team simulations, and web application security assessments.

I like building tools as much as I like using them — from network vulnerability scanners to honeypots and steganalysis frameworks — because understanding a system well enough to defend it usually means understanding it well enough to build a piece of it yourself.
