Freelancer Overview

I am an analytical and detail-oriented Applied Mathematics student with hands-on experience in data analysis, content evaluation, and information verification. My background includes working on academic research projects where I analyzed quantitative datasets, identified patterns, and ensured the logical consistency of data. I am skilled in data labeling, annotation, and quality assurance, with a strong ability to follow structured guidelines and detect errors or inconsistencies. I am proficient in using tools like Microsoft Excel, Google Sheets, and various AI platforms, and I excel at organizing and categorizing information for machine learning and AI training purposes. My strong attention to detail, logical reasoning, and ability to work independently make me well-suited for roles in AI data annotation, model evaluation, and prompt review.
