Back to original languageAbout Louis
Looking to leverage generative AI to build intelligent assistants, automate your processes, or enhance your internal data? I will guide you from A to Z in designing custom systems using LangChain and LangGraph.
💼 My Background
Previously a Data Scientist at Tabesto, I worked on concrete problems of automation and large-scale data processing, combining NLP, data engineering, and machine learning. Today, I offer this expertise to more agile and innovative freelance projects.
🚀 What I Can Do For You
• Design RAG (Retrieval-Augmented Generation) systems: ingest your documents (PDF, Word, Notion, Confluence, etc.), vectorize (FAISS, Chroma, Qdrant…), integrate into a LangChain or LangGraph pipeline.
• Create autonomous agents to automate business processes (lead qualification, customer support, document generation…).
• Integrate LLMs (GPT-4, Claude, Mistral, etc.) into your internal tools or products via API.
• Advanced orchestration with LangGraph: define complex workflows, manage states, conditional branching, task parallelization.
• Industrialization: containerization (Docker), deployment (Cloud / On-prem), API endpoint security, monitoring.
🧠 Approach
I take the time to understand your business needs, technical constraints, and business objectives. My goal is to build robust, understandable, and scalable solutions.
📩 Available for short or long-term missions, in-person or remote. I can also act as a technical consultant to structure your first POCs and conduct training sessions on using generative AI.
