Freelancer Overview

Education includes Bachelor of Science, 湖南大学 (2026). I have a solid foundational capability in data labeling and AI training data. Through my major in Information and Computing Science, I have studied core courses such as Mathematical Analysis and Optimization Methods, enabling me to understand the importance of annotation quality from both data distribution and model requirements perspectives. In the Customer Segmentation project, I independently performed data cleaning, feature extraction (RFM model), and fuzzy clustering analysis, developing a mature judgment for data anomalies, category definitions, and label consistency. Additionally, I am proficient in Python, Excel, and Power BI, and can write scripts to assist with data preprocessing and annotation quality checks. My experience implementing algorithms like KNN also helps me understand how labeled data impacts model training. My key strength lies in translating mathematical modeling and data analysis capabilities into systematic data quality control. For example, in the Customer Segmentation project, when applying fuzzy clustering to existing customers, I was able to identify boundary cases with ambiguous membership and provide personalized service labels accordingly. This experience in handling “edge cases” is especially critical for defining annotation rules and performing quality assurance in tasks such as image segmentation or text classification. Furthermore, my CET-6 score (433) and experience in multiple data visualization projects reflect my attention to detail and sense of delivery. I believe my mathematics background and end‑to‑end data processing experience can help teams establish more efficient and consistent annotation standards in the production, quality assurance, and management of AI training data.
