Had to program an entire ecommerce site for both a city soccer league and baseball league. Around 50 teams each. No planning or anything beforehand. They gave me around 4 days to complete the project. Once everything was squared away, of course they complained and said that half of the teams were wrong. So I had to stay until around 11 pm in the office fixing everything that Friday night. Of course everyone said it was my fault. I blame it on the lack of planning.
