Freelancer Overview

Since last year, I have contributed to the Math Frontier Project, Euler Project, and Titanium Project, working in multiple roles including content writer, reviewer, and rubric developer. My work has involved creating high-quality mathematics problems and solutions, reviewing modelresponses for correctness, and designing evaluation rubrics to assess mathematical reasoning. I have experience working across a range of topics, including algebra, combinatorics, geometry, number theory, and calculus. My background in mathematics enables me to identify subtle errors in proofs and solutions, maintain high annotation quality, and provide detailed feedback for AI model evaluation. I am particularly interested in tasks involving mathematical reasoning, problem solving, solution verification, and the development of high-quality training data for large language models.
