Freelancer Overview

Native Korean speaker with experience in Korean content writing, editing, product documentation, and digital content planning. Skilled in reviewing Korean text for clarity, fluency, tone, relevance, and user intent. Although I am at the entry level in formal data labeling and AI training, I have hands-on experience creating, reviewing, and improving Korean-language content across blogs, web pages, product documents, and user-facing materials. I am interested in Korean data annotation, LLM evaluation, AI response review, text rewriting, content quality review, and language evaluation tasks. I can follow detailed guidelines, work independently in remote project-based environments, and provide careful feedback on Korean-language outputs.
