I am a senior computer science / electronic engineer. I started in 1988 hacking video games on a commodore 64 (motorola 6502) by inspecting machine language stored in floppy disks tracks and sectors to find where they stored the number of lives of the game I was not able to finish so to increase it from usually 03 to 99 and I made it. My passion continued being hired in Anderse Consulting firm (later Accenture) as a analyst programmer, as I was good I became a Project Manager for very large sw projects, then Director of Information Management Service at Accenture for 10 years then I quit for Oracle then for Hitachi. now I enjoy as freelance the Python world to help small customers with data trasformation, star schemas and BI for those who just want to play with small data as small is much better than big. andrea.grianti@gmail.com
