Freelancer Overview

I’m a bilingual AI Trainer (Japanese–English) with experience in RLHF, data annotation, and content evaluation projects. Over the past year, I’ve worked on multiple AI training initiatives, including text rating, audio transcription, and search evaluation for platforms such as TELUS International and Scale AI. My background in healthcare product R&D and marketing gives me strong analytical and linguistic precision, which I apply to evaluate AI-generated outputs with a human-centered perspective. I’m detail-oriented, quality-focused, and able to follow complex guidelines accurately. I’m currently seeking new opportunities in AI model training, content moderation, or linguistic data analysis.
