I recently built an AI procurement and market-comparison assistant at Novation City that turns supplier invoices or typed requests into live price comparisons across eight Tunisian e-commerce sites.

I developed the system end to end: vision-language invoice parsing, resilient FastAPI search workflows, PostgreSQL/pgvector semantic search, scheduled catalog updates, and source-grounded LLM comparison reports.

I've also built a RAG chatbot over PDF documents from scratch, with explicit parsing, chunking, embedding, retrieval, and auditable grounded answers. My computer vision work includes plant disease detection and segmentation with YOLOv8, served through a FastAPI inference API.

Alongside my M.Sc. in Big Data & Data Science, I teach mathematics remotely and have written step-by-step solutions to more than 500 advanced problems for Photomath. I bring strong mathematical foundations, clear technical communication, and practical experience across NLP, LLMs, computer vision, and backend deployment.
