// about

Cybersecurity student at Full Sail University, graduating January 2027 with a B.S. in Cybersecurity. Focused on both defensive and offensive security — building detection infrastructure, writing tools in C++, and working through real-world attack scenarios in CTFs and labs.

I hold CompTIA A+, Security+, and CySA+, with the CCNA and eJPT in progress. My work spans SOC detection engineering, threat simulation, and systems-level tooling.

Fluent in English, French, and Arabic. Based in Winter Park, FL.

SOC Detection Lab
writeup ↗
Multi-VM homelab running Wazuh SIEM with custom detection rules mapped to MITRE ATT&CK. Simulated attack scenarios — credential dumping, lateral movement, persistence — then built and tuned alerts to catch them. Documented end-to-end in a lab report.
Wazuh MITRE ATT&CK Detection Engineering VirtualBox
Web Infrastructure Lab
Deployed and hardened a multi-VM web application stack on Azure. Covered network segmentation, firewall configuration, access control, and basic hardening against common web attack vectors.

HTB / CTF Writeups
read ↗
Ongoing documentation of Hack The Box machines and CTF challenges. Covers web exploitation, privilege escalation, and more. Written to be technically precise and educational.

Philosophy

I write about some philosophical subjects — everything from deep inquiries like questioning the study of philosophy itself, to more practical relevant things like poking holes in our understanding of validation. Published on Substack: Mathasophia ↗

Guitar

I love playing the guitar! Currently learning the Rick & Morty "For the Damaged Coda" song.

Writing

I love writing, in general. Not only the aforementioned philosophy, but also screenplays, books and short stories.
