01 / ABOUT
Systems first.
Security always.
My background spans military technical systems, Windows enterprise administration, cybersecurity, and increasingly Linux and offensive security.
I built my technical foundation troubleshooting systems where reliability mattered, then carried that mindset into enterprise IT and systems administration.
Professionally, much of my experience has been in Windows environments. Outside of work, I deliberately build and operate Linux infrastructure to deepen my understanding of networking, services, containers, DNS, remote access, and system internals.
Cybersecurity is the direction tying those disciplines together. I am developing hands-on offensive security skills through labs, tooling, enumeration, exploitation, and OSCP preparation with the long-term goal of moving further into penetration testing and offensive security.
This site documents both sides of that path: the experience I already bring and the technical work I am actively doing to move forward.

07 / APPROACH
Know what the system is doing — not just which button makes it work.
Troubleshooting is easier when the underlying system makes sense. Whether I'm working with Windows, Linux, networking, containers, or security tooling, I want to understand what is happening beneath the interface.
That same mindset drives my move toward offensive security: enumerate carefully, understand the environment, test assumptions, and learn from every failure.
