I started my career as a software developer in 1983, when I wrote custom Apple// software applications for the customers of a local computer shop.
In the following years I developed software as free-lance for the Apple platform (Lisa, Macintosh, Newton) using the major development tools available like Microsoft Basic, TML Pascal, MPW Pascal, MPW C++, MacApp, NewtonScript.
I wrote the first releases of Mac Edil for Italsoft, an Italian company, specialized in software for builder account.
Just few months before the acquisition of NeXT by Apple I started to study Objective C and investigate the OpenStep platform.
