Dude, I set up wild crap with Autohotkey, for a job. I had it logging in to vendor websites where it would pull up clients, compare contact info to our local system, check if recent payment had been made, pull appropriate client docs (if not already in our local system), and leave notes for me before moving onto the next client on the list. I had AHK doing most of the job I was hired for.

Thankfully, the multiple vendor websites made occasional changes to their layouts, color schemes, etc. so all my methods of navigation would inevitably break, requiring me to maintain it.

I was also building stuff where it would automatically fire off an email at certain points if there was a special change to tell the client about, if payment wasn't seen on the vendor site by certain deadlines, etc.

That job eventually fell through for unrelated reasons (they moved me off that to somewhere they needed me more, and several years later got pushed out of that position and the company entirely).

Where do I get a job that let's me build that stuff again?!

Autohotkey? Naw, you wanna setup a daily cron job to read and replace every one of your common typos with the correct spelling. That's the way, trust me.

Edit: Daily cron job typo correction.
