Yann Cohen – Data Analyst

About Me

Data Analyst and Psychology graduate based in Martinique, a French Caribbean island 🌴🏖️.

Equipped with an adventurous spirit and strong analytical thinking, I believe no project is ever too small. From data cleaning and visualization to advanced predictive modeling, my focus is on delivering actionable insights that drive meaningful decisions.

Open communication is the key for any successful partnership 👌.

When I’m not building dashboards, you’ll probably find me at around 12k feet, jumping out of an airplane (60 jumps and counting...) 🪂.

TOURMAN

Wait, who's Tourman?

Early on, when I started traveling, I adopted this last name as if to let people around me, and mostly myself, know that this journey is no joke. Let me (try to) start from the beginning.

Somewhere in Australia back in 2017, I got this idea of riding a bicycle the entire length of the globe from north to south. A few months later, on August 21st, 2018, I left Brooklyn, NYC, and headed north. Alaska north.

I returned south and started zigzagging between the coasts, deserts, and valleys of this vast country before eventually entering Mexico. In the next few months, the world was about to change - COVID. I found myself in mid-2020 in Costa Rica, unable to continue further south, I decided to go back home. The bike stayed there.

Fast forward to November 2024 (well, you can read in the sections above what I did all this time). I flew back to Costa Rica and re-launched my bike trip with the intention of reaching my destination: Ushuia, fin del mundo.

I'm in no rush. As one of the podcast titles down below rightfully stated, I don't just ride, I zigzag. So I found myself riding the high Andes, the mighty Amazonas, and - at the time of writing these lines - preparing for a boat-hitchhiking adventure to take me to Martinique, a French Caribbean island.
