I was born in Milano (Italy) in 1955 and graduated in
Physical Sciences
in 1979 at the University of Milano.
I worked for a lifetime in IT, mainly on compilers,
mathematical
software and real-time control.
I always had a passion for mathematics and puzzles to
which now I can
devote more time, as I retired.
I maintain a site about numbers (www.bitman.name),
unfortunately in
Italian.
