Freelancer Overview

I’m currently a contributor and reviewer at Outlier Remote in France, where I improve AI models in mathematics, language, and coding. Over the past several months, I’ve taken on projects in French (France, Switzerland, Canada, Belgium) and English (United States, United Kingdom), focusing on refining AI outputs and ensuring that each dataset meets a high standard of accuracy. I find it especially rewarding to catch nuanced edge cases and maintain a consistent approach across a variety of languages and markets. Before working in AI, I spent over six years in product management, sales, and marketing with industry-leading companies—experience that sharpened my ability to align projects with user needs and manage cross-functional teams. I’m fluent in French, Spanish, and English, and I have a good command of Portuguese and Greek. This international perspective has helped me adapt quickly to different work cultures and collaborate with diverse teams. Bringing together my AI experience and my product management background allows me to contribute both technically and strategically to each new challenge.

Labeling Experience

Since early 2024, I’ve been refining AI models in mathematics, language, and coding by reviewing prompts, evaluating generated responses, and providing constructive feedback. My tasks range from classifying text snippets to crafting prompt–response pairs and verifying code correctness. I also cross-check outputs for consistency and clarity, helping to maintain rigorous quality standards. Working closely with multilingual datasets (French, English), I also ensure that each labeled set meets the client’s accuracy requirements.
