Freelancer Overview

As a certified data-labeling professional studying Astronomy and Chemistry at the Korea Science Academy of KAIST, I already pair rigorous scientific training with hands-on annotation work across text, image, and multimodal datasets. I have designed clear labeling guidelines, automated quality checks with Python, and kept error rates below 1 % while contributing to projects that range from telescope imagery aligned with JPL ephemerides to chromatographic profiles and multilingual chat logs for large-language-model fine-tuning.
