I mainly work with [Borland/Inprise/Embarcadero] Delphi and Oracle. In the last 2-3 years I started also developing Android applications using C# (using native android APIs, not MAUI/Xamarin Forms)

In my past there are Visual C++, C++ on linux (and HP-UX), C, Pascal, Modula-2, Z-80 and 6502 ASM programming.

I have written the internal application framework (based on delphi and oracle) used by the company I work for to write their leading product.. and it is a huge piece of software: 10 programmers are currently working on it. I am still responsible of all the tecnical aspects of the developement and lifecycle management of such software.
