I have been a web developer for the past 20 years, and have specialized in ecommerce for the past 16. I am most familiar with Java/JSP/Javascript/SQL/HTML5, but I have used many different technologies - including PHP, Perl, C++, shell scripting, and many more.
I enjoy solving complex problems, but also helping people understand what is wrong. For this reason, I am perfectly happy to teach people how to solve problems as well as simply providing a quick solution.
