Freelancer Overview

I am a mechanical engineering major with experience in data labeling and AI learning data quality management. I have contributed to various AI projects based on my Korean-English bilingual skills and content analysis capabilities. In the Outlier project, I reviewed and annotated over 1,000 AI-generated texts and evaluated them for factuality, logic, and guideline compliance. I was promoted to Reviewer and Trusted Reviewer in recognition of my achievements. I also have experience working with project managers to provide feedback to improve reviewer alignment and guideline clarity, and I am skilled in effectively identifying hallucinations, duplications, and ambiguities using internal QA tools. I have proven my ability to perform work quickly and accurately in various projects, and I have strengths in cross-functional collaboration and high-quality results.
