About

I'm a Principal Machine Learning Scientist at AWS, where I lead a team of scientists building AI agents that write code. Some of my work powers the Kiro Autonomous Agent.

Before diving into code generation, I worked on Amazon SageMaker, recommendation systems at Amazon Music, and various ML systems across Amazon's retail business.

At times, I also co-organize events for the broader ML community such as the AutoML Seminars and the workshops on Deep Learning for Code (DL4C at NeurIPS and ICLR 2025).

I did my PhD in Applied Mathematics at the University of Milan under the supervision of Prof. Nicolò Cesa-Bianchi and Prof. Claudio Gentile, mostly focusing on online learning and bandits on graphs.

Fun fact: Some of my jokes made it into this book (not on LinkedIn, obviously).
