Building the career fair website for my college while in school. There was a lot to be desired, but thousands of students had accounts and uploaded resumes, hundreds of companies registered and paid over $500k per year through the site for registration fees/sponsorships/etc. I was given a single physical server that was locked in a closet somewhere on campus. It was ~2001, so I had to build pretty much everything from scratch on the LAMP stack ( and keep it running ).

I have since built systems orders of magnitude more complex, but you always keep a special place in your first.
