I was hired firstly to take care of the institutional website http://csa.osa.org.br
I did the complete redesign of the application and visual identity of the website and applying web standards techniques I could put the web site at the first page of google when searching for the school terms on São Paulo area.
The changes increased the speed of loading page and reduced the bytes transferred of each request reducing the cost with bandwidth that was charged separated at that time, and wasn't cheap.
I also did the setup of a new servers structure and reduced the monthly costs in 80%, from R$ 10k to R$ 2k.
