About Me

I'm a cybersecurity practitioner with hands-on experience configuring security tools, performing vulnerability assessments, and enforcing NIST-aligned controls. My background includes developing executive-level awareness training, conducting 50+ scans using InsightVM, and tuning network defenses across cloud and enterprise environments. I’m passionate about GRC, blue team work, and building secure systems that actually make sense. Right now, I’m looking for my first full-time role in cybersecurity — if it involves risk, compliance, detection, or defense, I’m in.

Outside of work, I train and compete in Brazilian Jiu-Jitsu and unwind by playing guitar. This site highlights the projects I’ve built, the skills I’ve sharpened, and the lessons I’ve picked up along the way.

“If you don’t have control, you don’t have jiu-jitsu.” — Rickson Gracie
