Hi, my name is Edin and I am 25 years old.
I am from Croatia originally but I have been living in Germany for 6 years now. I moved to Germany to study. At the moment I am living in Stuttgart and I am studying fashion-design.
I could say, I have a lot of knowledge of english because through the years I collected a lot of different terminology from different types of subjects and advanced business world. I finished my high-school diploma in english, I studied International Business Management in english, in the past I tutored elementary school kids as-well.
