This site was built to manage the contributions for a governor in Wisconsin. I also built the front-end site to accept donations that accepts PayPal and credit card payments.

I built the back-end and front-end from the ground up using the Zend Framework.
The back-end has many parts including managing bank transactions and millions of dollars in donations, sorting their contacts setting up custom forms and many other functions.
I built the front-end in a way that many other politicians can accept donations while using the same code base and they are able to set up their own look and feel for their forms.
