"We exist without skin color, without nationality, without religious bias... My crime is that of curiosity." — The Mentor, The Conscience of a Hacker (Phrack #7, 1986)

10+ years in systems and network administration. I've built, maintained, and broken infrastructure — and I've learned more from the breaking than the building.

The why and the how matter. Always. That's not a methodology — it's the only honest way to operate. If you don't understand what's underneath, you don't understand anything at all.

Linux is my daily driver — not by habit, but by conviction. It rewards curiosity, punishes assumptions, and gives you the kind of low-level control that other systems hide behind a friendly face. I/O redirection alone is worth the price of admission.

• Offensive Security — penetration testing methodology, vulnerability research, red team concepts. You cannot defend what you don't understand how to attack.
• Systems & Network Administration — a decade of routing, switching, firewalls, VPNs, server infrastructure, and keeping things running when they'd rather not.
• Development — not a developer, but getting there. Mastering Python. Building familiarity with Rust, JavaScript, Go, and the C family — because understanding languages means understanding what's actually running.
