Freelancer Overview

I am a Japanese native speaker with hands-on experience in AI training data and evaluation across RWS, Welocalize, and Lingotribe. My expertise includes search quality assessment, image annotation, audio/video evaluation, and Japanese language content evaluation using OpenAI's Feather platform, including high-accuracy transcription with dialect recognition. What sets me apart is my combination of native Japanese proficiency, AI application development experience (nihongoi.com), and content creation background with 450,000+ subscribers, enabling culturally-aware, high-quality data annotation for Japanese language AI models.
