Freelancer Overview

I have hands-on experience with data labeling and annotation across text, image, video, and audio modalities. For text, I review AI-generated prompts and responses in Cantonese, evaluating language accuracy, localization, truthfulness, and overall helpfulness. For image and video data, I perform detailed tagging, including product identification, location tagging, and other relevant metrics to ensure high-quality annotations. For audio data, I review AI-powered phone helpdesk interactions in Mandarin Chinese using Python-based workflows, validating whether the system triggers the correct prompts and delivers accurate, timely responses.
