What I’m focused on
Cybersecurity and network engineering with an emphasis on real-world infrastructure: segmentation, routing/switching, hardening, and controlled security testing.
Download ResumeHow I work
I aim for documentation that an engineer can reproduce quickly: clear objectives, exact commands/configs, verification steps, and troubleshooting notes.

I’m currently interested in building and documenting Red Team infrastructure in AWS and be able to perform Penetration Testing!
(in safe, controlled environments): attacker-style lab networking, C2 fundamentals, payload delivery workflows, and detection/visibility on the defensive side.
Note: When I write about offensive techniques, I keep details educational and focused on labs, verification, and mitigation.
Principles I follow
Reproducibility
If someone else can’t reproduce it, it’s not done.
