Freelancer Overview

As an entry-level worker in the data annotation field, I have gained experience across a wide range of tasks, including LLM translation, prompt writing to challenge models, reviewing and editing responses, rating model outputs, and providing detailed feedback on model performance. Backed by my native Korean skills and fluent English, I am confident I would be a valuable contributor to OpenTrain AI’s bilingual projects.
