Hi, I'm Nikita Chumak

UX Researcher from Warsaw

Since 2018, I have conducted user research across B2B, B2C, AdTech, and FinTech, using usability testing, in-depth interviews, surveys, and data analysis. Combining UX research with a background in Social Psychology, I bring a deeper understanding of the motivations behind user needs and actions.
