Who's Behind The Terminal

Born and raised in the Austrian Alps, I spent over a decade in the trenches of offensive and defensive security — from red-teaming to architecting zero-trust infrastructure for government.

My background bridges the gap between raw systems engineering and application security. I write code that breaks code, and build systems designed to withstand the attacks I devise for others.

When not chasing flags or writing exploits, I create or test enterprise-grade infrastructure and open source projects in my homelab.
