Hello, I'm
Data Science and AI Engineering student at École Polytechnique Sousse with hands-on experience building RAG systems, LLM applications, and data pipelines. Passionate about AI and full-stack development.
I'm a Data Science and AI Engineering student at École Polytechnique Sousse (graduating 2028) with full-stack development experience. I've built production MERN applications, RAG systems with hybrid retrieval, and LLM-powered tools.
I'm passionate about applying AI and machine learning to real-world problems — from document Q&A pipelines to agentic workflows. Open to relocation and available for AI/ML engineering, applied ML, or data science internships.
Some of my recent work — from RAG pipelines to full-stack web platforms.
End-to-end RAG pipeline with hybrid dense+sparse retrieval, RRF fusion, cross-encoder reranking, and LLM evaluation.
OCR food-label analyzer extracting ingredients and computing nutritional scores against WHO daily intake.
Responsive landing page for the Horizon Impact student group with CTA flows and product showcasing.
Real-time ticketing platform with live chat, role-based views, and task tracking for team collaboration.
Restaurant and cafe management system to manage orders, reservations, products, and users with an intuitive dashboard.
Web app for managing club members and membership dues with secure auth, dues tracking, dashboard, and reports.
ML model using Decision Tree Classifier with hyperparameter tuning to predict diabetes based on health indicators.
Expected graduation: 2028. Coursework: machine learning mathematics, probability, statistics, algorithms, Python for data science.
Built a full-stack project-management platform (MERN) used by a 5-person team to coordinate 30+ tasks, with real-time messaging and role-based access control (Admin / Manager / Member). Designed 10+ reusable React components; reduced ticket-status update latency by ~40% through client-state optimizations.
Delivered a production e-commerce site supporting 50+ products with search, cart, and secure checkout; reduced product load time ~30% via MongoDB indexing and lazy loading. Improved UI responsiveness across 3 breakpoints; contributed 20+ PRs and performed code reviews (Git).
Graduated with honors. Final year project: Project Management Web Platform (MERN, MVC).
