Typical programmer, wholeheartedly believing they can build a something in an afternoon and be done with it. I don't care how well you scoped the project -- it almost always takes longer. It's naive and all this does is cost businesses time and money. It's usually much more economical to go with a third-party than to build everything in-house, which needs to account for the costs of new-feature dev and long-term maintenance. I have an entire business running on that premise.
