Started as a local social network in the days before Facebook and StudiVZ (it's german clone), it was a quite successful community with round about 100.000 registered members and more than 30M PI's/Month at its peak. I was completely responsible for the technical part, starting from the server setup to the development with a php backend and even the design part. As we struggled with very low hardware due to nearly no budget at the start, i've learned a lot about caching and performance optimization with given resources :)
