About Julien

Currently a student in a leading French engineering school specializing in digital technology, I am offering my skills in AI, statistics, and coding for your projects this summer.

My education combines strong scientific rigor (modeling, complex algorithms) with the ability to deliver concrete, fast, and profitable tools for your business.

What I can do for you:

Machine Learning & Algorithms:Design and training of custom predictive models (classification, forecasting, scoring, NLP) to automate your decisions (Python, Scikit-Learn).

Data Analysis & Dataviz:Cleaning complex databases, manipulating large volumes of data, and creating clear dashboards (SQL, Pandas, PowerBI) to make your numbers speak.

Web Scraping & Lead Extraction:Retrieving and enriching targeted data from the web (Google Maps, directories, competitor sites) to provide you with ready-to-use prospecting files.

Scripts & Automation:Developing scripts to eliminate repetitive tasks and connect your tools.

Why work with me?
My training has taught me to quickly acquire skills in complex subjects and to be autonomous. No sloppy code: I guarantee you thorough, documented work that is immediately usable by your teams.

I am highly responsive and available immediately for short-term assignments or to support your Tech projects.
