Omar Al ReesiExploring how computers work, one project at a time.

Computer science student at GUtech in Oman. I like understanding what happens underneath the code, and I build real software along the way.

About me

I'm Omar, a computer science student from Oman who can't stop taking things apart to see how they work.

I started out self-taught, building websites and web apps. Studying computer science at GUtech is now filling in everything underneath: data structures, memory, and what the frameworks were hiding from me.

These days that curiosity mostly goes into C++, machine learning written from scratch, and tools I want to exist.

Alongside my studies I still build real software: products of my own, platforms for clients, and a part-time role at a software company.

Currently exploring

  • C++
  • Machine learning
  • Systems concepts

Building products

  • Laravel
  • PHP
  • React
  • Next.js
  • TypeScript
  • Filament
  • Spring Boot

Data

  • PostgreSQL
  • MySQL
  • Supabase
  • REST APIs

Infrastructure

  • Linux
  • Docker
  • Coolify
  • VPS
  • Git

Things I've built

Real products and platforms, for companies, organisations, and myself.
