Freelancer Overview

I am an experienced specialist in text analysis, jailbreak prompt generation, and audio/image evaluation. My strong understanding of Japanese culture—and ability to clearly explain cultural nuances in English—has made me a standout contributor on platforms such as Outlier, DataAnnotation.tech, and Mercor. On all three platforms, I was promoted to reviewer within a few months and have since worked on a wide range of projects focused primarily on LLM evaluation.
