He competes with Krystyna Klimczak.
They are the 2007 Polish national silver medalists.
They have competed internationally on the junior level at both Junior Grand Prix events and at the World Junior Figure Skating Championships and received the host wildcard entry to the 2007-2008 Junior Grand Prix Final, where they placed 9th.

Although they placed ninth on the day, they were later moved up a spot to an eighth-place finish at the 2007-2008 Junior Grand Prix Final following the retroactive disqualification of first-place-finishers Vera Bazarova & Yuri Larionov due to a positive doping sample from Larionov.
