Freelancer Overview

I began my AI career as an Orb Operator for OpenAI’s Worldcoin project, where I managed biometric iris-scanning devices and assisted users with secure World ID registration. This role required strong attention to detail, technical accuracy, and user communication in both English and Korean. After that, I transitioned into AI training data annotation, working with DataAnnotation to create and evaluate prompts for large language models (LLMs). I later joined Telus Digital, where I performed video quality comparison, image data preprocessing, and user-engagement evaluations to help improve AI perception models. My experience combines multimodal data labeling (text, image, and video) with a bilingual skill set and a solid understanding of how humans interact with AI-generated content.
