Welcome!

If you’ve landed here, chances are you came from my LinkedIn. This is a quick recap of a fun little solo project I did to explore the most in-demand skills in the data and AI job market in France, as of May 2025.

It was a simple end-to-end (E2E) project, meaning I did everything myself: from gathering the data to exploring it and building the visualizations.

The idea

Turn the chaos of job listings into a clear visual map of the data and AI landscape:

  • Scrape 2,500 job postings using keywords related to data, AI, machine learning, and specific tools and technologies such as Power BI and PyTorch.
  • Feed it all into a well-prompted LLM to turn messy job descriptions into clean and structured data.
  • Visualize the results as a galaxy of skills, where connections and gravity fields emerge naturally.

✔️
A simple pipeline, built solo, that reflects what a full data team does at scale: Data Engineers collect and clean, Data Scientists find patterns, Data Analysts turn them into insights, Data Architects model, PMs frame the needs, and CDOs? Well, someone has to look important in meetings 😄.

Quick explanation of the result

Once cleaned and structured, the data practically organized itself. Visualizing it as a skill galaxy revealed not just which tools and roles dominate the market, but how they connect and cluster in real-world job offers.

Each node represents a skill. The bigger the node, the more frequently it shows up in job postings. The thicker the links, the more often two skills appear together (think SQL & Power BI).

From this emerges a really cooool structure with three main constellations:

  • At the top, the Data Science zone, orbiting around the star that is Python.
  • At the bottom left, the Data Engineering universe, where a DevOps constellation cuts across the map.
  • On the right, the Business Intelligence territory, lit up by a SQL supernova, gently fading into quieter yet essential areas like Governance and Product.

What started as raw text became a map of the Data & AI ecosystem! Alive with connections, gravity, and meaning. 🌌

💪
A mini end-to-end project, just the way we like it: a bit of scraping, some LLM magic, and a cool data viz to wrap it up.
