I started writing software for Windows in 1992, first in Borland Pascal and assembly, a few years later in Windows C/C++. Started developing for Windows 3.1, then WFW3.11, NT 3.51, NT4, W2K, XP, Vista, Win7, Win8, Win10 all in C/C++, writing GUI, MultiMedia, Server or lower level applications and also some drivers. Also wrote software for all mobile platforms, especially navigation software. Started programming in Basic/assembly on a CPC464 in 1988.
