Right now, they bill me at $82 / hour. I believe that is scheduled to go up to $84 in July, although everything is always up for negotiation.
1. 10 years experience
2. Officially, our contract renews every fiscal year (and the customer can fire us at any time, so no guarantees), but have been working with the same customers for 8 years running now.
3. The stack has gone through one major shift - when I started, we were an IBM shop, so DB2 for database, COBOL batch and CICS onlines, and we actually coded the onlines and some batch in EGL, because in 1990 the powers that be thought that was a good idea. We did a couple odds and ends in .NET / SQL Server as well. Since they replaced the main system about 3 years ago, we are almost exclusively a .NET / Oracle operation. Still have some SQL Server databases around for when someone wants really old data. And a lot of work is done in one of our units with Access databases, but I have very little to do with that, and hope to keep it that way - mostly just get called in when the Access "expert" can't get something to run fast enough and so we'll give it a go in Oracle, or needs debugging help.
