Projects

A selection of my work in entrepreneurship, data science and mathematical research. Open a project for details, figures and reports.

Le Carnet de Prépa — Launching an E-commerce Product End-to-End

Designed, produced and sold a physical study notebook for French prépa students. Full-stack e-commerce site built with Claude Code, automated Stripe-to-print-on-demand pipeline, Meta Ads. 340+ sales and €9,000 revenue in one year.

Credit Default Prediction — Crédit Agricole Personal Finance & Mobility

Machine learning model (logistic regression, gradient boosting) estimating customers’ probability of default on a 30-million-row dataset, plus a SAS-to-Snowflake database migration for pipeline automation.

Working on the problem at the Johns Hopkins Department of Mathematics

Entropy Methods for the Fractional Porous Medium Equation — Johns Hopkins University

Six-month research stay at the Johns Hopkins Department of Mathematics. Proved an exponential convergence rate toward the stationary profile using entropy methods, and wrote the research report in LaTeX.

Neural network approximation with uniform vs gradient-aware sampling

Neural Networks for High-Gradient Functions — Research Apprenticeship at I2M

Research work-study at the Institut de Mathématiques de Marseille: neural network theory, TensorFlow experiments, and a gradient-aware sampling method that improves approximation where the target function varies sharply.

Automating MT-191 Billing Processing — Natixis

Custom VBA tool that extracts, transforms and visualizes MT-191 billing data for the Cash Management team. Built from business users’ requirements; processing time cut from 2 hours to 3 minutes.
