Abaddon – Ethical Hacker / Cloud Systems Engineer

Offensive, defensive, and everything in between – backed by real labs, NCL rankings, and production EHR systems.

I think like an attacker and build like an engineer. My work spans red teaming, web app exploitation, reverse engineering, and cryptography through the National Cyber League, and day-to-day hardening of Linux and AWS environments that run real healthcare workloads.

About

I’m Abaddon — a cloud systems engineer and ethical hacker who treats every environment like a CTF that just happens to pay the bills. I’ve secured EHR systems in production, torn apart vulnerable web apps, and led teams through high-pressure competitions.

My edge is the ability to move fluently between offense and defense: weaponizing misconfigurations, then codifying the fix in automation, monitoring, and policy. I live in the terminal, think like an attacker, and document like an engineer.
