Bio

I am the co-founder & CTO @ Upstream. My love for software started when I was only a teenager: I developed @ Dino Gaia, one of the most popular online French consumer games in the 2000s, registering a million visits every month. I've since built extensive technical hands-on and leadership experience across multiple sectors, including ride-hailing, fintech, and legaltech. I was most recently the VP of Engineering @ Doctrine before it got acquired.
