About me: 
I am physics and ICT teacher in ‘’28 Nentori’’ secondary school Burrel, Albania. Despite the fact my main degree are Physics, I have always loved Informatics since it was held for the first time as a subject in university. Understanding that Informatics is another passion of mine and worth investing for, I got a masters degree in Informatics and when Informatics entered the school curriculum, I began to teach classes of ICT. I try to give my best and continue to share as much as possible to students my knowledge and passion for computers and technology. Having this as a strong weapon I coordinate projects and take part in competitions in which technology makes us feel closer, better and more determined.
