What I'm looking for

I want to contribute as a Data Annotation and AI Training Specialist, leveraging AI data labeling, LLM evaluation, RLHF workflows, and quality assurance to support scalable machine learning systems and improve AI model accuracy.

I’m a detail-oriented Data Annotation Specialist with 1.5 years of experience supporting AI data labeling and LLM training through Toloka AI. I evaluate AI-generated responses for accuracy, relevance, safety, and quality, while categorizing, reviewing, and validating large datasets according to detailed annotation guidelines.

I also contribute to RLHF workflows by providing structured human feedback to improve AI model performance, and I strengthen outputs with quality assurance checks focused on consistency and high annotation accuracy. I thrive working independently in fast-paced remote environments, maintaining confidentiality and compliance while delivering reliable, guideline-compliant results.
