Hard to say who's actually doing this work. I DO know that in Chicago, the demand for computer programmers for customer-facing portals is extremely high. Espcially since the Motorola split. The handset company was absorbed by Google and moved to the Merchandise Mart, and the police radio company moved from their huge campus in Palatine to another downtown building, just across from Union Station. The West Loop is chock full of these 20 to 30ish engineering geeks making umpteen squillions for these two companies alone.
