Freelancer Overview

I have hands-on experience in AI training data and data labeling through multiple international platforms, including OneForma, DataAnnotation, Outlier. My work has involved audio segmentation, transcription, annotation, and data quality evaluation, often under strict guidelines and accuracy thresholds. I am experienced in tasks requiring precise timestamping, linguistic analysis, and consistent labeling across large datasets, which has strengthened my attention to detail and ability to follow complex instructions. As a native Russian speaker with strong English skills, I specialize in language-focused AI tasks, ensuring high-quality outputs aligned with linguistic and cultural nuances. I am highly adaptable, quick to learn new tools and guidelines, and committed to maintaining data integrity and quality standards. My combination of practical annotation experience, multilingual proficiency, and strong responsibility allows me to deliver reliable and accurate results in AI training workflows.
