Zhanna was born in 1969 in Murmansk, Russia. She studied at the printing school in Ufa, but spent most of her life in Mozyr, Belarus. She was registered as a sole proprietor, was passionate about fitness and healthy eating, and traveled extensively.
In 2023, Sereda received an invitation from a Polish company and has lived and worked in Poznan since then.
Plans for a quiet life abroad were interrupted upon her return to Belarus. Zhanna last posted anything on social media in December 2025—she was detained shortly afterward.
