I am Marco Montanari, a coder, developer, software architect, visionary. Simply put, I’m a strange engineer who loves Artificial Intelligence (when it was still calle Machine Learning), Philosophy, Sociology, Theology. And I love urbanistics and architecture (because both are expressions of the previous list).
