Safir started his career in 2011 in a band called Cherik ("guerrilla"), releasing several singles. He's also collaborated on some of their albums. In 2015 he left Cherik to start the label Mellistream with Saeed Dehghan with the goal of developing new literature in Persian rap.
Because of his academic degree, which is in dramatic literature, he is one of the pioneers of using theatrical and drama-driven lyrics in Persian rap. Safir's ability to play with Perian language rules and distort words is what defines the relationship between his lyrics and his beats.
He has written and performed most of the rap parts in Tafigh (Vol. 2).
