Freelancer Overview

I specialize in AI training and evaluation, with hands-on experience assessing large language models in both French and English. My work includes evaluating model outputs for instruction following, truthfulness, style, and localization, as well as optimizing prompts across a wide range of formats such as Open QA, Chatbot, and Brainstorming tasks. In addition to AI evaluation, I bring a strong background in fullstack web development using technologies like HTML, CSS, JavaScript, React, Node.js, and MongoDB. My ability to combine technical skills with linguistic precision allows me to contribute high-quality data labeling and model refinement across multilingual and technical contexts.
