Julien Letessier

Principal Engineer

I’m a software geek: I build things with code, like web applications, platform tools, search engines, or even tiny crypto utilities. I’ve previously had fun as an engineer, scientist, architect, manager, and start-up founder.

These days I mostly help other people building software here at Deliveroo!
