Around 2004, Halyna Churilova encouraged him and Oleksandra Nazarova, also a single skater from Kharkiv, to form an ice dancing partnership.

They won the bronze medal at their next JGP event, in Tallinn, Estonia, after placing sixth in the short and third in the free dance.

[4] Making their senior international debut, Nazarova/Nikitin won the silver medal at the Warsaw Cup, a Challenger Series event in November 2014.

After winning the Ukrainian senior national title, they were named in Ukraine's team to the European Championships, held in late January 2015 in Stockholm, Sweden.

At the end of the same month, Nazarova/Nikitin competed on the senior level at the 2015 World Championships in Shanghai, China; they ranked seventeenth in both segments and overall.

[4] Deciding to change coaches, Nazarova/Nikitin joined Igor Shpilband and Fabian Bourzat in Novi, Michigan in late June 2016.

They finished seventh at their Grand Prix assignment, the 2016 Trophée de France, and ninth at the 2017 European Championships in Ostrava, Czech Republic.

Due to their result, Ukraine qualified a spot in the ice dancing event at the 2018 Winter Olympics in Pyeongchang, South Korea.

[4] After this season ended, they left Igor Shpilband in Novi, Michigan, and began training only under Fabian Bourzat in France.

Assigned to two Grand Prix events, they placed eighth at Skate America and ninth at NHK Trophy.

[4] Nazarova/Nikitin began the season at the 2019 CS Lombardia Trophy, where they placed fourth in both programs to win the bronze medal overall.

They went on to win the bronze medal at the 2019 CS Ice Star, where they set a personal best in the Rhythm Dance and overall score.

[4] Between 2019 CS Ice Star and the 2019 Bosphorus Cup, Nazarova/Nikitin announced that they had ended their partnership with Fabian Bourzat.

[19] Following the Olympics, Nazarova and Nikitin returned to their homes in Kharkiv, which shortly afterward became a central point of conflict when Vladimir Putin launched an invasion of Ukraine.

[21] They received considerable support from skaters in other European and North American countries, notably entreaties from French Olympic champion Gabriella Papadakis that they attend the 2022 World Championships in Montpellier despite their training disruptions.

[23][24] Nazarova and Nikitin took to the ice wearing the Ukrainian national colours and received a huge ovation from the crowd for the rhythm dance segment, where they placed sixteenth.
