I graduated in 2026 from École Centrale Marseille, a generalist engineering school, where I followed the Data Science and Decision-Making option.
In 2024, I spent a semester as a Visiting Researcher at Johns Hopkins University in the USA, working on the convergence rates for a Nonlinear partial differential equation. I worked during 6 months in a fully international environment.
I then did a gap year, splitted in 2 parts. As an intern at Natixis CIB, I automated a data billing process for the Cash Management team with, cutting processing time from 2 hours to 3 minutes. In 2025, I joined the French Army’s Grandes Écoles Partnership a 6-month officer program. I was trained at Saint-Cyr Coëtquidan and at the Artillery School in Draguignan, then incorporated 4 months co-supervising a 30-soldier section at the 40th Artillery Regiment. It taught me field leadership, how to keep a team moving under pressure and an adaptability to a the military & defense culture.
On my last year of study, completed my degree as a Data Scientist apprentice at Crédit Agricole, building machine learning models to predict customer default. I also migrated large databases to Snowflake as a part of a data pipeline automation initiative from the team.
I have an entrepreneurial mindset. On the side of my studies, I founded Le Carnet de Prépa a study notebook for prépa students that I designed, produced and sell online myself (zone-prepa.com). It reached 340+ sales and €9,000 in revenue in its first year.
What I enjoy most is owning a problem from design to execution and seeing a concrete result. I’m now looking for a role at the interface of technology and operations, where I can deploy, coordinate and deliver, in AI, defense tech or tech companies.
