Programming for over 30 years. Started as a tyke. BASIC (not Visual-BASIC!), THINK C, C, C++, Assembler (Z80, 68K, TI DSPs, SHARC), Bash, Java, Python, CORBA, Jython, Scala, Oracle, MySQL, MS-SQL, and so on.
Commodore VIC-20, Osborne, MAC OS, OSX, Linux, IRIX, Solaris, AIX, Digital UNIX, and a couple of small device drivers and embedded OS's I've written myself. I even wrote some Windows code in my darker days.
These days I'm focused on computational logistics and have founded a company as a basis for that focus (Kinema Logic GmbH).
