Freelancer Overview

Since starting my data labeling career in 2025, I have worked on a range of annotation tasks, including audio transcription, emotion recognition, and text evaluation. Although I am new to this industry, I bring a strong foundation from my previous background in emergency medical services and business management, where precision, consistency, and responsibility were essential. My bilingual skills (Korean-English) enable me to contribute effectively to projects that require both accuracy and cultural understanding.
