At that time I learned the same but for renting an apartment in Geneva area… but that’s another story :).

Past April 2021, I had a great opportunity and I took it. Hoping that my professional experience could help people that are just finishing their studies in Computer Science, I’ve performed a talk for the Escuela de Ingeniería Informática, which belongs to the University of Oviedo.

In this article, I’ll talk about this experience and why I think it’s important that a close collaboration between universities and companies happens. Engage!
