Calx0r | Offensive Security

Breaking things for the better

Portfolio LinkedIn

#whoami

I’m Calx0r, a Network Administrator who approaches infrastructure with an offensive security mindset. I focus on secure configuration, segmentation, and reliability, backed by hands-on penetration testing and vulnerability analysis experience.

I study how networks and systems break so I can build them stronger.

Methodical. Adaptable. Calm at the console.
