About me

Originally from Marseille, I am currently completing my Master's degree in Computer Science at EPFL, with a specialization in Data Analysis and AI. I love exploring tech and discovering new things, whether that means working on machine learning models or building interactive web applications.

When I am not behind a screen, you can usually find me swimming, hitting the slopes for some skiing, or capturing the world through photography.
