What I'm looking for
As a dedicated freelance AI trainer and data annotator, I have developed strong expertise in refining AI outputs, optimizing search results, and ensuring cultural and linguistic accuracy. My work with companies such as Outlier, Appen, and Alignerr has strengthened my ability to adapt to diverse contexts and deliver high‑quality results in both French and English.
With a solid background in data labelling, voice acting, and prompt evaluation, I excel in maintaining quality, safety, and relevance across projects. I also take pride in reviewing and improving peer contributions to uphold high performance standards. Open to expanding my skills, I am ready to train for new roles where I can bring value and continue to grow.
