2018–2019 season

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, Nguyen/Kolesnik.^[3] 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 podium. Ushakova/Nekrasov beat the bronze medalists, Khudaiberdieva/Nazarov, by about 6 points, but the race for the gold medal was extremely tight. The gold medalists, Shevchenko/Eremenko, beat Ushakova/Nekrasov by a margin of only 0.01 points.^[4]
