Freelancer Overview

I am a detail-oriented English-Korean linguist and AI data specialist with hands-on experience in data labeling, annotation, and large language model (LLM) training. My work includes evaluating and editing Korean language data for cultural and grammatical accuracy, analyzing complex prompts, and refining guidelines to enhance AI model performance. I have managed urgent data collection and translation projects, performed machine translation post-editing (MTPE), and ensured high-quality standards for both text and voice data. Skilled in CAT tools like Trados and Smartcat, as well as MS Office and Google Workspace, I specialize in IT, gaming, and AI-related content, consistently delivering precise results under tight deadlines. My professional-level English proficiency (TOEIC 900+) and experience collaborating with international teams enable me to contribute effectively to global AI and localization projects.
