Lucio // Lucio

I go by Lucio online. I'm currently Head of Information Technology at Demirbilek Group in Cairo — overseeing cybersecurity and enterprise IT operations across multiple locations. Alongside that, I'm a content creator, self-directed security learner, and builder who's been making things on screens since I was a teenager.

Before terminals, there was water. I was a swim coach at 14, working abroad across Lebanon and Egypt, away from family, figuring things out independently. That self-reliance never left — it became the engine. I went through web & graphic design, enterprise IT support, team management — and somewhere in all of that, I got obsessed with a different question: not just how do I build this, but how can someone break it?

That obsession led me to cybersecurity. No traditional degree. Just real curricula, a terminal, and the discipline to follow through. Documenting the climb.

01

I was six years old when my father brought home a computer. Not a good one — mid-low class, slow, the kind that took forever to boot. But when that screen lit up, something happened to me that I still can't fully explain. I sat in front of it and didn't want to leave. Not because of games. Because of the machine itself. How does this work? What's inside it? How does it know what to do? That obsession never left. It just grew up with me.

"A cheap computer my dad bought when I was six years old changed my entire life. That's the honest truth of how all of this started."

I was 14 when I left home. Not dramatically — just the way life went. I moved to work as a swim coach across Lebanon and Egypt, away from family, figuring things out alone. That independence became the foundation. I went through coaching, web and graphic design, enterprise IT support, team management — and through all of it, I kept coming back to the same question I had at six: how does this work, and how can someone break it?

That question led me to cybersecurity. No traditional degree. Just real university curricula mapped out and studied module by module, a terminal always open, and the discipline to show up every day. I've passed CompTIA A+, Network+, and Security+ exams — pursuing official certificate issuance. The knowledge is validated and in practice daily at Demirbilek Group, where I currently lead IT operations. The paper follows when it follows; it was never the point. Understanding was.

Living across Syria, Lebanon, and Egypt shaped how I think. Moving between cultures, working independently from a young age, being exposed to different ways people build and use technology — it rewired my perspective. I don't see borders between disciplines. Design thinking, system architecture, network behavior, offensive security — they all connect. That cross-domain wiring is the thing I'm most grateful for.

This site is the public record of that obsession. Every course, every note, every CTF writeup is me turning around and pointing at the path for whoever comes next. If you're self-taught, underfunded, living far from home, or just convinced you can figure it out on your own — this site was built for you. The climb is real. Document it.
