Samir is the brother of bantamweight Issa Samir and is the team captain of Ghana's national team Black Bombers. He won the African Championships in the welterweight division in May 2007. At the All-African Games he knocked out Hosam Bakr Abdin, but lost the final bout to Rached Merdassi.
He missed the world championships as he could not make the weight and had to jump two weight classes to light-heavyweight to qualify for the 2008 Summer Olympics because Ahmed Saraku was the established middleweight. He managed to achieve this in the second qualifier.
