At the 2010 Winter Olympics, she surprisingly qualified 16th in the parallel giant slalom, but lost in the round of 16 to Marion Kreiner, finishing 16th.

She is also a two-time silver medalist of Winter Universiades in parallel giant slalom: in 2011 in Turkish Erzurum and 2017 in Kazakh Almaty.

In February 2019, she ranked 6th in the parallel giant slalom event at the World Championships which was the best ever result for Ukraine at snowboarding competitions of the highest level.

Later on, Dancha won against Polish Aleksandra Król and 2018 Winter Olympics bronze medalist German Ramona Theresia Hofmeister.

Nine years ago, Dancha (Chundak back then) won against Zogg in the final of the parallel giant slalom at the Junior World Championships.
