Freelancer Overview

I am an AI training data specialist with hands-on experience across the complete data pipeline, contributing to projects on Toloka, Mercor, Luel, Tarmack, and Quikrsignal. My work spans image labeling and object annotation, side-by-side image quality comparison, audio transcription and annotation, and egocentric POV video capture, all completed to strict platform specifications with consistently high acceptance rates. Backed by a Computer Engineering background, I bring both technical understanding and a quality-first mindset to every task, whether identifying objects in images, assessing the clarity of AI-generated visuals, or accurately converting spoken content into structured, annotated text. What truly sets me apart is my experience in AI response evaluation and RLHF-style tasks through Mercor, where I rated and compared chatbot outputs across dimensions including accuracy, relevance, helpfulness, tone, and safety. I have assessed responses across diverse categories, from factual Q&A and code explanation to creative writing and conversational dialogue, providing structured written justifications that directly support model refinement. Combined with my video capture expertise and multi-platform track record, I offer a rare breadth of AI data skills that covers both the perception and language sides of model training.
