Yauheni worked as a foreman. He was one of the administrators of the Telegram channel "Petrykau 97%". The channel discussed the elections as well as the place and time of peaceful protests for those who disagreed with the vote count. In June 2021, a court declared the channel extremist, and in November of the same year the Ministry of Internal Affairs designated the group of citizens united by it an extremist formation. On the day of that decision, Yauheni was detained for three days, and on December 30, 2021, he was taken into custody.
In March 2022, Yauheni was found guilty in a criminal case initiated under the articles "Creation of an extremist formation or participation in it" and "Inciting racial, national, religious or other social hatred or discord" for administering that channel and reposting a message about the riot police from the Nexta Telegram channel, and sentenced to imprisonment in a penal colony.
Jürgen Coße, a member of the Bundestag, became Yauheni's symbolic godfather.
According to human rights defenders' estimates, he was released in August 2026 after fully serving the sentence imposed by the court.
