I provide infrastructure support for some very large applications, one of which is the largest Dotnet application in the southern hemisphere... you'd probably know of it, or it's related websites.
I also provide support within the organisation for similar sorts of applications.
I utterly adore my job. I get paid very well to my mind for what I do, some days i spend doin absolutely nothing (and to be honest, i hate those days)
other times it's really busy and really noisy.. if the stuff hits the rotating air mover, i thrive.
It's also the sort of job where even if i'm not on call, i'd respond if called in for a major outage.
I get to work with all sorts of technology, and my immediate team leader, and director above that, are VERY talented and good at what they do, so I learn heaps from them.
Since a couple of other team members have gravitated elsewhere, I've had much more opportunity to become involved in the more senior work..
all in all, i love my job, i really really do.. who else is going to let me play with millions of dollars of top of the line server equipment.
