Freelancer Overview

Seasoned mathematician with over five years of experience in the core disciplines of creating and evaluating complex data, directly applicable to AI training data curation. My expertise lies in designing challenging mathematical prompts across calculus, statistics, and optimization, and architecting detailed scoring rubrics to assess solutions for correctness, completeness, and logical rigor. I am proficient in the full data lifecycle, from authoring step-by-step solutions and few-shot exemplars to executing precise, rubric-based evaluations, providing corrective feedback, and tagging content with granular metadata. I have successfully applied this skillset in academic and e-learning contexts, developing a large repository of tagged problems and exemplars for university-level courses. My advanced mathematical background (MSc, Applied Mathematics), coupled with C2 English proficiency and rigorous research experience, enables me to parse complex guidelines, ensure utmost precision, and contribute significantly to the development of reliable and high-performing AI models. I am adept at rapidly switching between tasks of problem creation, evaluation, and iterative instruction improvement.
