I've found out quickly that working on large projects is a very different game than the midsize sites I was used to: there are half a dozen developers working on the same front-end code. Perfection is hard to come by when deadlines are looming. There are dozens of stakeholders, there's code from external sources you can't control, page elements that you can't control, and so on.
