I'm well versed in content management systems such as Wordpress and Drupal. JQuery, Bootstrap, CSS, XHTML, Javascript, all the standard web tools are also in my toolbelt. I originally specialized in database driven, PHP integrated sites with an administrative back end to enable simple updating for non-web savvy clients. Now that simpler systems are available, I support whichever CMS system the client needs and can also help with training. And I can still customize anything.
