I also designed Copilot Studio agents for dashboard proposals and notebook reviews, and use RAG, LangChain, and Azure OpenAI to build AI-powered assistants and automations.
At Logistics Group Andreani, I developed machine learning models for fraud detection and claims prediction; one model reduced fraud cases by 40%, and another supported an 85% accuracy result and a 30% reduction in claims. I also worked on productionizing models with MLOps practices, including experiment tracking, versioning, deployment pipelines, and monitoring.
