Freelancer Overview

I bring hands-on experience as an AI Trainer, where I worked on Japanese voice data annotation and review, contributing to high-quality AI training datasets. My background also includes extensive content creation, editing, and quality assurance as a published author and blogger, with a keen eye for detail and accuracy. I am skilled in digital tools such as Logic Pro and Davinci Resolve, and I have a strong understanding of language and communication from my work as a radio personality and website creator. My diverse experience enables me to efficiently manage, label, and review data for AI projects, particularly in document, text, and audio domains.
