Freelancer Overview

I am an experienced data annotator and data analyst with a strong background in AI training data, having worked on multimodal annotation tasks for computer vision and natural language processing projects. My expertise includes labeling images, diagrams, and video frames, as well as live speech-based AI evaluations in both English and Traditional Chinese. I am skilled at ensuring data quality, privacy compliance, and temporal consistency, using tools like CVAT, Label Studio, Doccano, Loom, Audacity, and Google Sheets. My experience also extends to managing annotation workflows, performing QA reviews, and collaborating with teams to maintain high standards. With a solid foundation in data analytics, SQL, Python, and Power BI, I bring a detail-oriented and process-driven approach to every project, consistently delivering accurate and reliable datasets for AI/ML model development.
