Mirzoev began skating in 2007 after an ice rink opened in Vladikavkaz.[1][2] As a singles skater, he was coached by Alexandr Mugdusov in Vladikavkaz, by Nadyr Kurbanov in Rostov-on-Don (2011–13), and by Alla Piatova in Saint Petersburg (2013–14).[3]
Mishina/Mirzoev were awarded gold at both of their 2016–17 JGP assignments, in Saransk, Russia, and Dresden, Germany. They were the top qualifiers at the JGP Final and won gold at the event, which was held in December in Marseille, France.[5]
In January 2017, Mishina stated that they would likely split, due to disagreements, but that they intended to complete the season.[6] She said that he was struggling with her weight but that it was not possible for her to lose more.[6]
