Freelancer Overview

I am a Computer Science and Mathematics engineer from Paris-Saclay with a strong analytical background and a growing expertise in AI training data and data labeling. My work focuses on creating and refining complex rubrics, annotation guidelines, and advanced prompts—particularly in French—to ensure high-quality datasets that support the development of reliable AI systems. With a solid foundation in both mathematics and computer science, I bring precision, logical rigor, and problem-solving skills to every project. In addition to my current role in data annotation technology, I have prior experience as a QA and Data Analyst intern, which honed my ability to detect inconsistencies, maintain data integrity, and apply structured evaluation methods. My combination of technical knowledge, linguistic adaptability, and attention to detail allows me to contribute effectively to AI training workflows, ensuring that outputs align with nuanced quality standards.
