Nekrasov began learning to skate in 2004. He trained as a single skater until 2010; he then switched to ice dancing. He and his first partner, Polina Velikanova, competed together during the 2011–2012 season. He skated the following season with Maria Oleynik. Nekrasov and Polina Kalinina skated two seasons together, 2013–2014 and 2014–2015. In 2015, he teamed up with Arina Ushakova. They are coached by Alexei Gorshkov and Maxim Bolotin.
Ushakova/Nekrasov started their season by competing in the 2018 JGP series. At their first JGP event of the season they won the gold medal in Kaunas, Lithuania. They were ranked first in both the rhythm dance and the free dance and won the gold medal by a margin of more than 6 points over the silver medalists, Avonley Nguyen / Vadym Kolesnik. Their rhythm dance, free dance and combined total scores at that competition were the highest scores achieved in an international junior ice dance competition at the time, though since surpassed. At their second JGP event of the season they won another gold medal, now in Yerevan, Armenia. Again they were ranked first in both the short program and the free skate. Ushakova/Nekrasov also upgraded their earlier short program, free skate and combined total World record scores. With two JGP gold medals they qualified for the 2018–19 Junior Grand Prix Final. At the Final Ushakova/Nekrasov won the silver medal after placing second in the rhythm dance and first in the free dance. They were part of a Russian sweep of the ice dance's podium. Ushakova/Nekrasov beat the bronze medalists, Elizaveta Khudaiberdieva / Nikita Nazarov, by about 6 points but the race for the gold medal were extremely tight. The gold medalists, Sofia Shevchenko / Igor Eremenko, beat Ushakova/Nekrasov by a margin of only 0.01 point. Following the Final, Ushakova/Nekrasov were again defeated by Shevchenko/Eremenko at the 2019 Russian Junior Championships, winning the silver medal after second-place finishes in both segments. In late February they won the 2019 Open Ice Mall Cup. Their final event of the season was the 2019 World Junior Championships, where they unexpectedly placed fourth in the rhythm dance after hitting only two of the eight keypoints on the tango pattern dance. They dropped to fifth place overall after placing fifth in the free dance.
2019–2020 season
Ushakova/Nekrasov missed the first half of the season, including the Junior Grand Prix, due to Nekrasov undergoing and recovering from leg surgery. They returned to competition with a victory at the Golden Spin of Zagreb, and then competed at the Russian Junior Championships, where they placed second behind Shanaeva/Naryzhnyy. Their silver medal at junior nationals led to their being assigned to compete at the 2020 World Junior Championships in Tallinn, Estonia. They placed fourth in the rhythm dance there, hitting only three of the eight keypoints on the Teatime Foxtrot pattern dance. Fourth in the free dance as well, they finished fourth overall.
