I have gone through a very rich and varied career, working professionally and voluntarily from many very different positions: after being a student, I was an employee at big multinational companies, I've been a teacher and professor at many private courses and at public university, I've been and still act as a consultant, I've always been an entrepreneur (managing companies for decades), and I have been contributing now for more than three decades on a voluntary basis to a variety of IT-related and social organizations, allowing me to learn a lot about public policies and cultures in over 50 countries. I'm also an author of many books, in various areas (including IT, sociology and spirituality).
