Freelancer Overview

Education includes Bachelor of Engineering, 大连工业大学 (2025).I have hands-on experience working with AI training data and end-to-end data labeling across text, image, and categorical datasets, supporting machine learning and NLP model development. My work includes annotating, categorizing, and refining raw data, ensuring strict adherence to labeling guidelines, quality standards, and consistency rules to eliminate bias, errors, and ambiguity. I am proficient in classifying intent, sentiment, entity recognition, and content moderation labeling, as well as auditing and correcting labeled datasets to maintain high accuracy for model training and fine-tuning. What sets me apart is my strong attention to detail, ability to quickly learn and follow complex labeling protocols, and consistency in delivering large volumes of high-quality annotated data under tight deadlines. I excel at identifying edge cases, resolving labeling ambiguities independently, and collaborating to align with project requirements. Additionally, I understand how clean, well-structured labeled data directly impacts AI model performance, allowing me to prioritize data integrity, uniformity, and usability throughout the entire data preparation and labeling workflow.
