Freelancer Overview

I have experience in AI training data projects, including text-based LLM response quality assessment, voice-based chatbot response assessment, audio transcription, and image data annotation. In these roles, I designed complex prompts to guide LLMs in generating accurate responses, evaluated generated outputs for naturalness, tone, contextual relevance, and localization, and transcribed Korean audio recordings for AI datasets. I also classified images containing cars and people and refined annotations to ensure accurate labeling. As a native Korean speaker fluent in Japanese with professional-level English, I bring strong multilingual capabilities to projects involving language and speech data. Combined with my background in chemistry and biology research and experience in scientific manuscript preparation, I approach AI data annotation with meticulous attention to detail, analytical skills, and a commitment to delivering high-quality datasets for model training.
