NASA :: Intelligent Systems
This site is built on a Content Management System which I wrote and maintain. This is no simple PHP/MySQL CMS. It makes robust use of XML/XSLT, a complex Application Framework and Ouput Caching. The core features include News Publishing, Calendaring, Templated Sub-sites, and method of mapping the relationships of Business Units.

NASA :: Ames Open Source Repository
NASA finally got approval to release software under the OSI approved NASA Open Source Agreement. I was lucky enough to be recruted to develop the pilot site. The back end of this site runs on relatively simple MVC patterned Tomcat/Postgres application. The front end is good old JSP/Beans and a couple of servlet filters for cacheing. The site has been Slashdotted twice and currently maintains about 300 concurrent users at all times due to the popular WorldWind application..

Euro World
Euro World designs living spaces based upon old world architecture. Andres Conde and I teamed up to design for them a Content Management System and Shopping Cart solution which allows end users to navigate floor plans, buy them designs. Technologies used to drive this site are PHP, Flash, and AJAX.

MoritexUSA
The United States division of Moritex was looking both to update the look and feel of their site and to gain control over the management of their content. Andres Conde and I teamed up provide them with this solution. The site is PHP/MySQL application based on a framework I developed for such applications, with an XHTML/CSS front end. There are number of little tricks in here you may find useful so please view source.

Emailsmiling.com
When I first got this site at my previous employeer it would barely load. You will note that now, even on a modem it loads quite quickly, the result of some serious revision to all 3 teirs of the application. Aside from being a basic greeting card site, emailsmiling.com allows mass mails to lists which can be imported from most mail applications, allows users to create their own address booksk, and provides mechanisms for the administrator to design and upload customized designs for specific users.
