Mariana Nechyporuk

I’m a native Russian and Ukrainian speaker with an advanced level of English, working at the intersection of AI language testing and professional translation. I specialize in manual testing of AI models with a focus on language capabilities, as well as high-quality translations between English, Russian, and Ukrainian. I have hands-on experience working on RLHF (Reinforcement Learning from Human Feedback) projects, helping fine-tune AI model behavior to align with human values and expectations. This includes ranking model outputs, providing nuanced feedback, and improving naturalness, safety, and overall quality of responses. In my AI work, I test models across different formats, such as text-based chatbots, voice assistants, and image recognition tools, ensuring they understand and generate language naturally, accurately, and appropriately. I verify grammar, tone, intent, and context in both scripted and unscripted interactions. As a translator, I focus on localization, cultural nuance, and natural flow, delivering content that sounds native, whether it’s marketing copy, app content, user interfaces, or educational material.
