Dan Lellouche

Hello, I am Dan Lellouche, a freelance Senior Data Scientist & Data Engineer, specializing in Generative AI, NLP, and Machine Learning.

I help companies transform their data into robust and industrialized AI solutions, with a direct impact on their business.

🔹 Key Expertise:

• Generative AI & Agentic AI: Optimized RAG, multi-agent orchestrations (LangChain, Langfuse, Phantom, OpenAI API).

• Advanced Machine Learning: NLP, Computer Vision (YOLOv5/YOLOv8), time series (LSTM), Reinforcement Learning.

• MLOps & Cloud: CI/CD (GitLab CI/GitHub Actions), Docker, Azure, AWS, GCP, vector DB (Azure Cognitive Search, FAISS, Pinecone).

• Data Engineering: asynchronous pipelines, massive scraping (Bright Data, Playwright), Big Data processing (Spark, Polars).

🔹 Key Achievements:

• Club Med: Development of a strategic AI for procurement (automated market intelligence, Agentic AI for quotes, automatic room allocation via RL → reduction from 20h to 2h/week).

• Sobrico / AFDB (e-commerce): customer segmentation (+12% conversion), RAG chatbots (–40% support requests), sales forecasting (–15% stockouts).

• Matsuri: real-time dish detection via YOLO on video stream, deployed on AWS → production optimization and waste reduction.

• Cross-functional projects: automatic meeting summarization, voice AI for customer support (–30% support volume), automated generation of e-commerce product sheets (x5 productivity).

🔹 Methodology: pragmatic, ROI-oriented, and industrialization-focused approach. I build scalable, monitored solutions that can be integrated into business systems.

I speak French, English, and Spanish fluently, and I am available for both strategic missions (consulting, scoping) and complete technical developments.
