Freelancer Overview

I am an experienced AI data annotation analyst with a strong background in labeling, evaluating, and reviewing video, audio, and image data for interactive AI applications, particularly in Mandarin Chinese. My hands-on work spans multimodal data, including preference ranking of AI outputs, key information extraction from images, structured transcript creation, and UI contextual description, with a focus on large language model training and RLHF workflows. I have been promoted to reviewer roles due to my high-quality submissions and have earned recognition for my accuracy and efficiency in large-scale annotation projects. My technical skills include Python, JSON, and various workflow tools, and I am adept at ensuring precise, reliable training data for model fine-tuning and evaluation across diverse domains.
