About

Thanks for stopping by. Read below to learn more about myself and my background.

Guillaume Rabeau

Background

I'm a Business & Data student at Albert School (Paris), currently completing my Bachelor's Degree and admitted to the joint MSc Data and AI for Business at Mines Paris – PSL. I'm passionate about mathematics, data science, philosophy, cinema, and photography — always eager to tackle complex, real-world problems at the intersection of AI and business.

Beyond data, I've spent 11 years practicing drama at the prestigious Cours Florent in Paris, which has shaped my communication style, public speaking confidence, and creative thinking. I also enjoy writing — I've contributed to a YouTube channel that reached over 1.5M views on a single video.

Sports are a big part of my life: I practice gym, climbing, diving, and boxing. I see sport as a constant reminder to push your limits and grow. I'm also a photography enthusiast, comfortable with Lightroom, Photoshop, and Premiere Pro.
