I used test driven development (TDD) for these projects, using JUnit to create my test suite. Each of these products was developed solely by myself. They involved database design, including the creation of indexes and enforcement of referential integrity in order to achievement maximum performance results. Each product provides extensive inline/API documentation for ease of reuse and maintainability.

jQuery Panels Widget
jQuery Panels is a user interface jQuery plugin that utilizes the widgets provided by the jQuery UI open source project to present entry points (or windows) into the server data -- similar to portal technology. All interaction with Panels is done so using AJAX technology, backed by the jQuery library. The Panels plugin allows for extensive customization, providing many points in which client applications can plugin in custom functionality and UI behavior specific to their needs. The plugin uses jQuery and CSS style sheets to dress up the panel content with a uniformed look and feel -- allowing the developer of the panel to focus solely on the functionality and less on the UI.
jQuery, jQuery UI, CSS 3.0, HTML.
