So I just finished my first 40 hour work week.
And just an hour ago I had a meeting.

In that meeting I said pretty much this:
"Your old system is rubbish, I want to make a new one"
"Also we can't use the old framework"
"Also it needs to be in a different language that nobody knows here"

And they went for it!

At this point I think I can sell anything to anyone.
