Freelancer Overview

I am an analytical and detail-oriented professional with hands-on experience in AI model evaluation, data annotation, and RLHF-based ranking tasks. My background includes evaluating large language model (LLM) outputs for accuracy, clarity, safety, and usefulness, as well as providing nuanced qualitative feedback to improve AI performance and alignment. I excel at detecting logical inconsistencies, factual inaccuracies, and subtle errors across a wide range of domains, including STEM subjects, humanities, and general reasoning. With a strong foundation in mathematics, engineering, and technical writing, I am adept at applying structured evaluation rubrics and maintaining rigorous quality standards in data labeling and annotation workflows. My ability to adapt across diverse subject areas and deliver clear, actionable insights makes me well-suited for roles in AI training data and model improvement projects.
