🔹React 🔸Microsoft 365 / Azure ♦️Angular

I am 25 year old and I started my career 7 years ago, even though my passion and interest were born more than 12 years ago.

As a developer, I divide my time between the frontend development on Microsoft technologies and the in-depth analysis of the new Microsoft 365 / React technologies, together with the involvement on the various Italian and international communities, trying to give my contribution and to learn more every day.

Right now: learning more about AWS 😁
