Freelancer Overview

I have over 2 years of experience in AI data annotation and training data preparation. I have worked on text, image, and short-video annotation projects, as well as AI response evaluation and quality assurance tasks. I am experienced in following detailed guidelines, maintaining annotation consistency, and reviewing data quality to ensure reliable training datasets. I have experience working in both offline and remote environments, including web-based annotation platforms. I am familiar with data labeling workflows, response evaluation, data review, and quality control. As a native Chinese speaker, I am particularly interested in contributing to Chinese-language AI training and annotation projects.
