Shumskyi teamed up with Anastasia Galyeta in November 2008. After becoming the Ukrainian junior silver medalists, they were assigned to the 2009 World Junior Championships, where they finished 23rd. They placed eighth the following year at the 2010 World Junior Championships. In their third season, Galyeta/Shumskyi won silver and bronze medals on the JGP series, qualified for the JGP Final, where they finished seventh, and placed 13th at the 2011 World Junior Championships. During their last season together, 2011–12, they won two silver medals on the JGP series and placed 5th at the JGP Final but were later disqualified due to Galyeta's positive doping sample.
