Freelancer Overview

I have 6 months of experience in AI training and data labeling at DataFactory, a team of 12 members. During this time, I worked full-time reviewing TTS outputs and AI interview videos, ensuring that responses, facial expressions, eye contact, attire, and applicant profiles met evaluation standards. I also generated interview questions based on applicants’ resumes and verified the quality and appropriateness of these questions, contributing to accurate and effective AI training data. In addition, I participated in developing a Korean spell-check system, collecting large text samples, testing the system’s accuracy, and identifying errors for correction. I conducted monthly quality tests to ensure the system’s reliability. These experiences have strengthened my attention to detail, understanding of language processing, and ability to maintain high-quality AI training data.
