    Over the last few years, I have developped many custom wordpress themes. I also have a variety of useful code written, specifically with regards to creating forms. My immediate goal is to get work building wordpress themes from duplicating an existing Photoshop PSD file. I provide pixel perfect duplication, and can implement a wide variety of features, often using my own code - which save a lot of hassle in trying to learn and modify existing plugins. I am also taking some online courses @ Treehouse to improve my design skills.
