Freelancer Overview

I have direct experience transcribing, translating, and labeling structured data for language models in AI training data projects. Specifically, I focused on segmenting audio and video content and applying accurate labels to generate high-quality bilingual output in both English and Korean. This work required adherence to detailed annotation guidelines, consistent formatting, and a high level of linguistic accuracy, ensuring data suitable for AI system training and evaluation. I also have experience reviewing and validating labeled data for quality, accuracy, and consistency. This experience has developed the ability to identify subtle errors in segmentation, timing, terminology, and semantic preservation. I am particularly strong in attention to detail, independent quality control, and maintaining reliability across large datasets. This background allows me to effectively contribute to human-in-the-loop AI workflows, where accuracy and consistency are crucial.
