I am a detail-oriented Data Annotation Specialist with over two years of direct experience evaluating, annotating, and training AI models for Russian-language content. I consistently maintain high annotation quality and apply rigorous QA procedures to improve dataset accuracy.

At Yandex, I evaluated LLM responses for style, grammar, factual accuracy and policy compliance, providing corrected reference answers and structured feedback to refine model behavior. I maintained a >95% annotation quality score across assigned tasks.

In long-term projects I configured and fine-tuned models for automated content detection, analyzed false positives/negatives, and improved labeling taxonomies to reduce noise. I collaborate effectively with developers and linguists to align annotation guidelines with real-world use cases.

With 10+ years of leadership and operations management experience, I bring strong analytical thinking, process-improvement orientation, and disciplined execution to AI training initiatives. I am committed to continuous learning in AI/ML and to delivering high-quality training data.
