Jeff Hidalgo

Security engineer focused on offensive security and AI/LLM security. Based in NYC.

I'm building toward a career at the intersection of penetration testing and AI security. Currently studying for OSCP, running a home lab on Kali, and building tools that solve problems I actually run into.
