I build AI that
catches fraud &
reads sentiment.
AI engineer at Groupe Covéa, Paris. I lead fraud-detection models end-to-end, recovering millions of euros in claims, and build sentiment-analysis systems with fine-tuned LLMs that sharpen customer intelligence. Fine-tuning, LoRA adapters, prompt engineering, production monitoring: I own the full stack.
Expertise
Fraud Detection
Production fraud-scoring models for insurance claims at Groupe Covéa: several million euros recovered at MAAF, 75% alert precision, 3× faster alert handling. I lead the full lifecycle: framing with fraud experts, engineering, deployment, monitoring.
