Interests

Apart from being a student at Polytech, I enjoy most of my time following science-fiction genre movies and television shows, and listening Rock and Rap titles. I also spend a large amount of my free time exploring the latest technology advancements in both hadware and software.

I really like to travel and discover other cultures. I have already traveled to some countries in Europe: Spain, Italy, England, Montenegro and Greece in holidays. I also went to Canada for a semester.
