About me

I am a Senior Software Engineer at GUCCI.

Previously, I worked as a Research Software Engineer at Ospedale San Raffaele. I hold a Ph.D. in Computer Science and Engineering from Politecnico di Milano. Before that, I graduated summa cum laude from Politecnico di Milano in Computer Science and Engineering.

In my spare time, I enjoy playing basketball, drums and retro games.

From 2011 to 2016, I served as a teaching assistant at Politecnico di Milano in the following topics:

  • Advanced Web technologies: how to build Web applications using Spring, JSTL and JPA (slides here)
  • Mobile applications: introduction to Android development (slides here)
  • Computer science principles: principles of programming in C++11 and above (slides here)
  • Digitial image processing: introduction to digital image processing and shape extraction
