[4] Shmuratko started learning to skate in 2006 at the age of four and a half years old after his parents signed him up for the sport on the advice of his doctors to improve the catarrhal diseases that he suffered from as a child.

Coached by Vira Volpova in Kyiv,[6] Shmuratko won two junior international medals: gold at the Ice Star and silver at the Santa Claus Cup.

The following month, he received medals at two senior events – silver at the Bosphorus Cup in Turkey and gold at the Ukrainian Championships.

Shmuratko started his season on the ISU Junior Grand Prix series, placing seventh in Poland, and winning the bronze in Italy with a personal best score.

[10] With pandemic-related travel restrictions limiting where skaters could compete, Shmuratko began the season at a European-only 2020 Nebelhorn Trophy, where he placed twelfth.

[11] After winning his third consecutive Ukrainian national title, Shmuratko competed at the 2021 World Championships in Stockholm, Sweden, placing twenty-first.

[17] Returning to Kyiv following the Olympics, Shmuratko soon found himself in the midst of Russia's invasion, with his home city being one of the largest points of conflict.

Despite the war and the resultant limitations on his training, Shmurtako still traveled to attend the 2022 World Championships in Montpellier, France, a journey that took three days.

"[18] Following the World Championships, Shmuratko spent April training at Club Olympique de Courbevoie in Paris, on the invitation of Ukrainian emigrant pair skater Denys Strekalin.

He subsequently relocated his training base to Oberstdorf, Germany, adding coaches Michael Huth, Robert Dierking, and Anna Bernauer to his team.

[25] At the 2024 European Championships in Kaunas, Lithuania, Shmuratko placed nineteenth in the short program, but twelfth in the free skate, moving up to fourteenth-place overall.

[14][26] During his free skate, Shmuratko notably wore a white shirt with a red splotch spattered across his chest to signify blood stains.
