Grumpy old developer with experience in C, C++, Java, .NET languages and any number of scripting type languages (Perl, Awk, PHP, Tcl, Python, Sh, ...)
On Unix (Linux, HP-UX, SunOs, Solaris, DEC, AIX etc) and Windows.
I know enough HTML CSS and JavaScript to be dangerous including some Bootstrap and React.
I can get stuff into and out of relational and noSQL databases (Mongo) through code I write or existing command line tools.
Comfortable with multi process / multi threaded systems (including shared resources)
I've even done some X11, assembly, pascal and cobol many years ago, but don't tell anyone about that...
