About Me
I help teams turn reliable data into decisions they can act on: understanding the business challenge, making sure the data behind it is trustworthy, and drawing conclusions that hold up. A graduate of the Master's in Information Systems and Decision Making at the University of Lille, I recently completed an internship at Ubisoft, working at the crossroads of fraud, payment and product, where I implemented a solution generating an estimated €100K in annual savings.
My Journey
My bachelor's degree in economics taught me to think in business terms: costs, risks, trade-offs. Specializing in data afterwards didn't take me away from the business side: it gave me the means to follow the reasoning through to the end. What motivates me is the full process: starting from a business question, making sure the data answering it is reliable and well understood, then drawing conclusions a decision-maker can actually use. That translator role between business and technical teams is exactly what I practiced at Ubisoft, working across fraud, payment, product and data teams.

Beyond Data
Outside of data, I am involved in volunteering where I mentor young people from disadvantaged backgrounds. This experience has taught me patience and pedagogy, qualities I believe are essential for explaining technical results to a non-expert audience. I am also a big fan of football and traveling. These passions fuel my curiosity and team spirit.
