Freelancer Overview

I am a native Korean speaker with over a decade of professional experience as a journalist and editor, which has given me a strong command of precise language and attention to detail. I have worked on AI training data projects for multiple companies, where I evaluated AI-generated outputs, assigned tasks, and assessed the work of others to ensure high-quality results. My background in writing, editing, and translation—combined with my expertise in both Korean and English—enables me to handle complex data labeling and annotation tasks, especially in natural language processing. I am also proficient in Excel, MS Word, and Photoshop, and bring a logical, analytical approach to problem solving thanks to my extensive editorial experience.

I have contributed to diverse AI projects, including conversational interactions with models, prompt design and testing, and controlled jailbreak experiments to assess model safety and robustness. The project I worked on with Anthropic lasted for several months, but I also participated in shorter projects that ended after a brief period. I don’t remember the names of all the companies involved.
