Data Scientist · Machine Learning & NLP

As a data scientist with two years of work-study experience in the banking sector, I have had the opportunity to work on projects where data has a direct impact on the business: evaluating the effectiveness of marketing campaigns, detecting transactions to crypto platforms, and optimising and automating credit risk and fraud reporting.

What drives me is both the technical depth of a well-designed model and the tangible impact it can have on operational business decisions. I’m particularly drawn to the fast-evolving nature of the field: tools keep improving, and the solutions we build are becoming increasingly ambitious. This constant need to adapt is both an intellectual challenge and a source of motivation for me.

I’m now looking for my first full-time role as a Data Scientist or AI Engineer, in a stimulating environment where I can continue to grow and take on new challenges.
