About me

Built from the
ground up.

I'm a Computer Science B.Sc. from Lebanese University – Faculty of Sciences (Class of 2026, GPA 83/100), based in Tripoli, Lebanon. My work spans the full stack — from bare-metal assembly and Linux internals to web platforms, databases, and interactive graphics.

I'm drawn to problems that require understanding how things actually work, not just how to use them. That's led to several projects, each built under a different set of constraints, each built with care.

What I know

Technical Expertise

A wide surface area - from x86 boot internals to React front-ends.

01 / Systems & Infrastructure
Where software meets the machine

Kernels, shells, and the wires between them — the layer beneath everything else I build.

Operating SystemsLinux System Administration Assembly LanguageShell Scripting Embedded SystemsNetworking CybersecurityCompilers & Theory of Computation
02 / Languages
A toolbox, not a favorite hammer

Picked to fit the constraints of the problem, from register-level control to rapid prototyping.

CC++Rust JavaC#Python PHPPrologJavaScript shell scripting x86-x64 Assembly MIPS Assembly Arduino
03 / Applications & Interfaces
Turning logic into something people can touch

Web back-ends and front-ends, desktop GUIs, and games — the layer users actually see.

Back-End Web DevelopmentFront-End Development ASP.NETFlask PHP CollectionRelational Databases PL/SQLGraphical User Interface (GUI) Java SwingC# WinForms RaylibGame Development
04 / Foundations & Practice
The structure underneath it all

Theory, math, and applied domains that shape how I design and reason about a system before writing a line of it.
