Web Developer

Freeman Marketing

May 2012 - November 2012

Freeman Marketing at that time was a small agency based out of St. Charles, MO. That specialized in building custom WordPress websites for local businesses. I was an in-office contractor during my time there.

I was responsible for converting Photoshop designs into WordPress marketing websites. Along with some content and SEO strategy. For part of the time there I was helping an intern web developer as well that was in school.

Bachelors - Web Design & Development

Full Sail University

November 2009 - March 2012

This was a fast-paced ~2-year bachelor program that was fully online. There I learned the fundamentals of web design, HTML, CSS, JavaScript, PHP and ActionScript.

With each class being about a month-long it taught me how to get up to speed on new topics. This was a good experience since it's much like the web industry fast-paced and there is always something new to learn. One of the biggest take away was to learn how to read documentation well. This will help you use any tool, language, framework, etc. not just the tools you are using.
