Freelancer Overview

I am an experienced Data Labeling Specialist with over two years of experience improving large language models (LLMs) through high-quality data curation and annotation. I specialize in Reinforcement Learning from Human Feedback (RLHF), prompt engineering, and complex text evaluation. My expertise includes grading AI responses for factual accuracy, identifying subtle linguistic bias, and drafting high-quality "ground truth" answers to train models on complex reasoning tasks.I have a proven track record of maintaining 95%+ data quality scores while managing large volumes of text. I adapt quickly to evolving taxonomy guidelines and regularly collaborate with cross-functional engineering teams to refine edge-case scenarios. My deep understanding of semantic nuances and data pipeline requirements allows me to deliver the precise, structured datasets necessary for deploying safe and highly capable AI models.
