Team composition: 2 PO, 2 Data Scientist, 2 Designer, 4 developers Gazodoc AI Project: Development of a RAG system to provide accurate answers to queries from Gazodoc (4000+ PDFs, Word, PPT, etc.), optimized by Query Transform, Hybrid Retriever, LLMReranker, memory, and metadata filtering. Integration of a learning system with user feedback (Like/Dislike). Creation of a general parser to extract images and tables using multi-modal. Retrodoc Project: Participation in the development of a RAG system based on a Graph Retriever and a note summarization system. Matomo Project: Design of a multi-agent workflow based on reflection and collaboration to extract data from the Matomo API via natural language queries. TelephonePRO: Development of a consulting system based on OpenAI's Whisper model's voice recognition and diarization to generate short summaries of recordings between clients and advisors. This system can also evaluate advisor services to provide suggestions.
