Stefan Janković was born in 2001 in Vranje. He lives with his brother, sister and parents in his hometown, where he finished elementary school and attends high school. He coached football for five years, and in an old video he admitted that he wanted to become a professional football player. After football, he trained “street workout”.
Stefan launched his “YouTube” channel in December 2015, and reached the first thousand subscribers eight months later. After he published various contents that are interesting to his peers and younger population on a daily basis, and since he cooperated with more famous colleagues, the number of reviews began to grow. The first 50 thousand subscribers reached in April 2017.
At the end of October 2019, the “Janko” channel has over 870 thousand subscribers, and the most watched clips are those in which he writes to a Serbian language teacher, tries to spend 24 hours in a supermarket, and teaches a monkey to ride a motorcycle.
