    Well before the World Wide Web was a common phrase as it is today, before most people even owned a home computer I was programming code in a variety of languages for a variety of network related projects back when you had to put the handset of a telephone on a 300 baud modem. Trillions of lines of code under my belt and a mind that functions like a computer processing unit I not only understand today's most popular programming languages, I know how the languages themselves came to be. I am an expert who has owned, operated or worked with thousands of technology based businesses over the past 25 years. More than a programmer, I am a valuable consultant to any business wishing to build or improve any online enterprise. My work is relatively fast, accurate, functional and most importantly well constructed based on your exact needs. I do all of my own work but will bring in experts if necessary to accomplish the goals of your organization. I am an American living in Pennsylvania.
