Hey, I'm Sofiane Oumeila — known online as sf0n.

I'm a cybersecurity enthusiast and tech content creator with a deep passion for understanding how systems work, and more importantly, how they break. My journey started with curiosity about how the internet works under the hood, and it quickly evolved into a full obsession with penetration testing, CTF challenges, network security, and low-level systems.

On this blog and portfolio, I document everything — from hands-on CTF writeups and vulnerability research to tool breakdowns and practical security tutorials. I believe the best way to learn is to do, and the best way to master something is to explain it clearly to others.

When I'm not hunting flags or writing posts, I'm tinkering with Linux, building small security tools in Python, or going down research rabbit holes I probably shouldn't have started at midnight.

sf0n is my corner of the internet. Raw, technical, and always learning.
