I can handle smaller projects for you completely - from analysis and Design over implementation and test up to the installation and hosting. In larger projects I cooperate gladly in your team and bring in my know-how and my ideas also.
In addition my self developed multi user multi site CMS empego.net even is a good platform for most diverse Web applications and could flow totally or partly into your application. From this project I gathered also to a lot of finished modules and components.
As frontend technology for my web applications I love to use the open source AJAX framework ZK, which has a rich ready to use component set and is easilyy to extend with customized components. A small overview of the possibilities is to be seen on the ZK Live demo application.
