About

I’m Franck Cédric Dienzou, an AI Trainer specialized in RLHF and factuality evaluation, where I assess the accuracy of LLM responses in both French and English and score them against detailed project guidelines. I enjoy working through ambiguous or borderline claims by checking against reliable sources, with the goal of reducing hallucinations and improving response reliability.

With a legal background (Master’s degree in Private Law with honors), I bring a structured and analytical approach to quality control, turning complex information into clear written summaries for different audiences. I’m also experienced in legal research and compliance-oriented work, and I like to learn how generative AI systems are built, evaluated, and continuously improved—while keeping data quality high.
