Freelancer Overview

I am a multilingual content specialist and AI trainer with hands-on experience in data annotation, content labeling, and quality assurance, particularly in multilingual environments. My work at Toloka and on various freelance projects has given me a strong command of dataset refinement, prompt engineering, and the evaluation of complex text data. I have contributed to projects involving audiovisual translation and localization, including subtitling for Netflix documentaries and mobile game localization, where I identified linguistic errors and enriched glossaries. With advanced research skills and a Master’s degree in Film Studies and Audiovisual Arts, I bring analytical rigor and contextual understanding to every project, ensuring high-quality, precise training data for AI applications. I am fluent in Russian, French, English, and Spanish, which allows me to work effectively across diverse datasets and cultural contexts.
