As a dancer, Weronika realises herself, among other things, in the association of independent artists and choreographers established in Warsaw, Centrum (w) Ruchu, which is a space for performing arts in Warsaw, created on the initiative of the Burdąg Foundation and located in the premises of the Wawer Cultural Center.
On the theatrical stage, Pelczyńska could also be seen in the play Fale (Waves), directed by Agnieszka Błońska in the Ochota Theatre in Warsaw. In 2011, Komuna Warsaw hosted the premiere of her solo performance Yvonne, Yvonne – a remix of the work of American choreographer Yvonne Rainer. In it, the dancer circles the empty stage several times in a steady run, then crosses the space, changes direction, after several minutes she enriches her trot with a set of exercises, and when she stops and tries to catch her balance, she smoothly moves to a series of exercises taken straight out of a ballet training room. The movement becomes more and more intense.
She is also active on dance stages in Germany, especially Bonn and Cologne. She can be seen in performances of Replay Swan, choreographed by Rafael Giovanola-Endrass of the Cocoon Dance Company, and Under Green Ground, choreographed by Stephanie Thiersch of the Mouvoir group.
