About Paul

Data / AI Engineer specialized in large-scale automation / scraping.


I help teams transform unstructured content (websites, documents, emails, public databases) into actionable data and time-saving automations.

Some concrete examples of what I can help with:

  • Automatic record enrichment:(company, product, contact): from a simple name or URL, retrieve structured information (image, description, keywords) directly injectable into an internal tool.
  • Information extraction from documents:(PDFs, emails, reports) to automate data entry, tagging, or document qualification.
  • Large-scale scraping and competitive intelligence:products, prices, competitors, prospects... with multi-source management (countries / currencies / categories) and recurring updates. I have notably built this type of pipeline on tens of thousands of products in the luxury sector, and on cross-prospecting INPI + LinkedIn to identify key executives and positions in a given sector.
  • Robust data pipelines:ingestion, cleaning, orchestration (Prefect), storage (PostgreSQL, MongoDB, Duckdb), cloud deployment to go from a script that works once to a system that runs by itself on hundreds of thousands of records.

I can alsobuild complete web applicationswhen the project requires it: FastAPI back-end, PostgreSQL database, authentication, cloud deployment, orchestration.

How I work:I prefer fixed-price projects, with a clear deliverable and deadline. I am available outside of regular business hours (early mornings, evenings, weekends), 100% remote.

Feel free to contact me, even if your needs are not yet fully defined.
