Pixel-art city: It's Nadjib, welcome

About Me

I'm an AI engineer and researcher based in Nancy, France, specialised in RAG, GraphRAG and agentic AI. I design systems where large language models reason over knowledge graphs: retrieval that understands structure, agents that plan and use tools, and LLMs that decide instead of guess. My work spans many domains, from biomedical knowledge graphs at Inria / LORIA and banking fraud detection with GNNs to medical imaging, Arabic NLP and autonomous ROS2 robots, and I take research ideas all the way to working systems.
