Gilmoreport is a stock market tip type site. Its condition when I started was over 50 plugins running the site and a heavy theme. I was hired to rebuild the site with performance in mind and adding many custom features to the mix.

The result was a completely new custom theme with a lot of custom templates and 1 single master plugin to control all of the features in the site.
Tons of custom hooks were added to the theme for filtering to specific needs according to the page or post category.
Integrating aMember membership control for paid membership content. All with a large performance boost.
