In 2014, while still a film student, she made her first film,
Sestra Zo about a former soccer player. In 2015, her first feature-length documentary,
Alisa in Warland, premiered at the
International Documentary Film Festival Amsterdam. It was co-directed by Liubov Durakova. In 2019, Kovalenko's experiences in Donbas lead her to begin a documentary film about the lives of teenagers in the war torn area and an opportunity five of them had to travel to the
Himalayas. In 2023, the final film
We Will Not Fade Away premiered at the
73rd Berlin International Film Festival. Kovalenko said that the experience made her feel "powerless as a documentary filmmaker." Her latest film
Traces is co-directed by Marysia Nikitchuk and focuses on conflict-related sexual violence (CRSV) due to Russia's invasion of Ukraine. The film premiered at the Berlin Filmfestival of 2026 and was nominated for best documentary feature. == Activism ==
