My name is Omar. Since I was young, I was interested in computers and programs, I always wondered how they were made. At 14, I got my first computer, very simple, and that's when I started in this world.
Later, I got my first job and built my computer with which I still work today. I decided to study a career in Computer Science, turning my passion into my profession.
Since then I have learned a lot, from scratch, in a self-taught way, making projects and applying it in different areas of my life.
