If it was originally supposed to do one thing, he probably has it doing something entirely different. Shannon began creating PayPal solutions more than three years ago using his original database- driven PayPal purchase system that integrated with Macromedia Dreamweaver UltraDev. Since then, he has gone on to implement unique fixes for common eCommerce problems using PayPal. He has written several tutorials and articles and has spoken on the topic of using PayPal in new ways. One of the first members of the PayPal Developer Network, he was added to the PayPal Developer Network Advisory Boards on its inception. He also served several terms as a member of Team Macromedia for their web development program Dreamweaver, which he uses in his daily PayPal development. His technical background extends back to the initial Internet boom, when he began picking up simple web design that evolved into web planning and programming using a variety of technologies, languages, and databases. Currently, he manages the PayLoadz Digital Goods eCommerce system that allows merchants to sell digital goods securely with PayPal. One of the first and most successful third-party solutions for PayPal, this system made headlines when it launched Madonna's "American Life" single higher on the Billboard music charts than any previous digital single (and he did it before selling digital music was cool).
