Olena was born two weeks after the Chernobyl disaster and her song 'Sweet People' reflects concern both for the effects of this disaster and for the world environment.

After the university of Culture and Arts, she signed a contract with Catapult Music in 2008. In 2010, Alyosha released an album (in English) with songs written by Dr. Peter B. Chykaliuk and his daughter Carrie.

On the 20th of March 2010, Olena won the Ukrainian National Final and so represented Ukraine in the Eurovision Song Contest of that year. She replaced Vasyl Lazarovych, who was originally chosen on December 29 of 2009 to represent Ukraine, but after some political changes his candidacy was withdrawn.
Olena would have sung her song "To Be Free", but since that song was already released, it was against the rules of the Eurovision Song Contest. So another, new, song was selected: Sweet People. In the finals, Alyosha finished 10th with 108 points.
