About Ludovico Bessi
Hey! I am Ludo.
I’m an ML engineer at Google Zürich, where I work on recommendation systems and ads ranking at scale.
I’ve spent years watching the delta between “how ML works in theory” and “how ML works at 3am when something breaks in prod. ”
This newsletter is where I close that gap.
Every issue is grounded in production patterns — the tradeoffs that don’t make it into papers, the architectural decisions that matter when you’re serving billions of requests, and the career moves that actually compound over time.
