I will build a custom ai chatbot with rag using python and llm apis

Hi, I'm Mathis an AI engineer with an MSc in Computer Science and

Artificial Intelligence (summa cum laude, UCLouvain) and a research

paper accepted at IEEE CoG 2026.

I build chatbots that answer from YOUR data not generic wrappers

that hallucinate.

WHAT YOU GET

- A working chatbot connected to your documents, website or database

- Clean, documented Python code yours to keep, in every package

- A simple web interface, ready to use (Standard & Premium)

- Deployment support, so it runs on your side and not just on mine

TECH

Python, LangChain, OpenAI / Anthropic / open-source LLMs, vector

databases (FAISS, Chroma, Pinecone), FastAPI, Docker.

HOW IT WORKS

1. You tell me what the bot should do and share your data

2. I send a short written scope, so we agree before I start

3. You get a working demo, then we refine it with your revisions

WHY ME

Five years of engineering training and published AI research not a

template seller. I explain every technical choice in plain language,

and I reply fast.

Not sure which package fits? Message me with your use case and I'll

tell you honestly what you need even if that's the cheapest one.
