Freelancer Overview

I am a bilingual (Korean–English) data annotator with hands-on experience in AI training data projects, specializing in image annotation, voice data collection, and linguistic tagging. I have contributed to multiple international labeling initiatives, including image labeling at CloudFactory, Korean voice recording at Outlier AI, and tagged transcription projects at OpenTrain. Across these roles, I maintained strong attention to detail, data accuracy, and consistency in line with predefined labeling and quality guidelines. With a background in marketing and communication, I bring a unique understanding of language, tone, and user intent to data annotation work. My cross-cultural and linguistic sensitivity allows me to refine data for both technical precision and contextual nuance—especially in projects requiring Korean–English bilingual understanding and natural language quality assurance.
