Calx0r | Offensive Security

Breaking things for the better

Portfolio LinkedIn

#whoami

Hello, I’m Brandon (Calx0r).

I came up administering and operating command-and-control systems where reliability, access, and timing mattered. That background shapes how I approach offensive security today, focusing on understanding systems end-to-end, validating vulnerabilities and testing how software behaves when assumptions break.

Methodical. Adaptable. Calm at the console.
