Targeting the intersection of offensive security and defensive engineering.

Operator's Log

I don't just break systems; I analyze the debris to build stronger ones. My work spans Red Team engagements, Purple Team drills, and Automated Detection. I translate technical vulnerabilities into business risk, ensuring that security is a verified constant, not a variable.
