    Front to End Web Development with Human Touch

    United States - Last active: 11/24/2014

    My career goals is to serve your website needs. My view is that website development is three parts - design, development and management. I am willing to do all three of those things for you in a friendly and communicative manner. I taught myself how to program at the age of 13, and taught myself web development during college while working one of the three jobs I had at the time. All my jobs since college have been web development gigs. I do this work because I love it! My portfolio is a bit small because most of my gigs have been corporate business-to-business jobs and are signed away on NDAs. However, I assure you I am professional, top notch, and will do my best to get you the best website that you want.
