About Yoann

Tens of thousands of documents to structure for an industrial client. PDFs everywhere, no classification, teams wasting time searching for information. I am setting up the automatic classification pipeline and the RAG architecture so that teams can query their documents in natural language.
What I do: I take your disorganized data (documents, emails, databases) and make it usable thanks to AI.
- Custom RAG Systems: Your teams ask questions to your internal documents. Example: an employee types "what is the test protocol for product X?" and gets the answer in 10 seconds instead of sifting through 200 folders.
- Data Collection: Web scraping, extraction, workflow automation
- Structuring: Automatic classification, data pipelines, cloud migration
Stack: Python, PostgreSQL/pgvector, LangChain, Google Cloud, Next.js.
