About Me

Security professional,
creative polymath.

Bilingual security professional with 8+ years of experience in IT and technical support. I bridge the gap between cybersecurity, software development, and creative arts — because limiting yourself to one discipline is overrated.

When I'm not hunting threats or writing code, you might find me producing electronic music, learning Japanese, or building AI-powered tools that make life more interesting.
