Freelancer Overview

I have hands-on experience in AI training data development through my role as a freelance data labeler for a Mandarin Audio Labeling Project. Over the project duration, I labeled and transcribed more than 12,000 short Mandarin audio clips, applying structured annotation rules for metadata, multi-speaker identification, and classification tagging. My work consistently met strict quality benchmarks, maintaining over 90% accuracy with less than a 10% rework rate. Beyond technical proficiency, I demonstrated strong time management and reliability by handling a 6-hour daily workload while ensuring timely and consistent submissions. This experience strengthened my attention to detail, linguistic precision, and ability to follow complex guidelines — all of which are essential for delivering high-quality AI training data.
