Freelancer Overview

Business Analyst with 4+ years of experience translating complex, large-scale data into structured, actionable insights across 10+ industries. My work consistently involves what AI training data demands most: precise categorization, pattern recognition, and clear annotation logic applied to messy real-world datasets. In my master's capstone, I directly worked with AI APIs to automate the segmentation and classification of 2,000+ financial products — giving me hands-on understanding of how AI models consume and rely on high-quality labeled data. I also generated plain-language advisory outputs for non-expert users, which sharpened my ability to label and structure information with end-user context in mind. This project earned the Outstanding Performance Prize for real-world applicability. My background in business analytics, statistical modeling, and cross-functional communication makes me a reliable contributor to data labeling and AI training tasks that require both analytical rigor and domain awareness.
