// 01 — about

who_am_i();

I'm Diego Lasorsa, a developer obsessed with what happens underneath the abstractions. While most programmers live comfortably at the application layer, I spend my time in assembly listings, kernel code, and bare-metal environments.

My interest spans from operating systems development to competitive cybersecurity. I build tools that live in the terminal, write exploits that dissect binaries, and occasionally ship a custom kernel patch just to understand why things work the way they do.

On the CTF side, I compete through mntcrl (mntcrl.it), a team I'm a member of. In 2026 I reached the national finals of OliCyber — Italy's cybersecurity olympiad — taking home the silver medal. I'm also a finalist of CyberChallenge.IT 2026 at the University of Bari. Reverse engineering, binary exploitation, and cryptography are my main categories.

Earlier I placed 2nd at HackInFest 2025 with a great prize, and trained on training.olicyber.it where I reached rank #76 nationally. Always pushing further up the leaderboard.

When I'm not CTF'ing I'm writing TUI applications, building OS toys, or reading Intel manuals for fun. Yes, that last part is intentional.
