After that I was in charge of supporting a website built with Java and the Spring framework, using both MySQL and Oracle databases, for customers worldwide.

My areas of expertise are PHP, MySQL & jQuery, but I am geek and there's never enough coding so I am working on learning new frameworks & languages.  less
