This is probably the most boring page here, but I know some people like to know this stuff. Specific software packages I know include.
Excel. I'm actually quite good at this. I've created a bunch of tools and "dashboard" type things to make people's lives a bit easier. I wish I was better at writing macros tho. (And I have a mental block with pivot charts.)
Word and the rest of the Microsoft Office suite
Notepad++ and Sublime (well let's face it, they're not hard, right!)
InDesign
Photoshop
Coding in HTML (still learning, as you will be able to tell from this website!) including CSS
SAP (or at least some bits of it)
Fortran (actually I've mercifully forgotten a lot of that. Does anyone out there still use Fortran??) and C Plus Plus (ditto).
