Ralf Sternberg is a committer to the Rich Ajax Platform (RAP), working for Innoopract in Karlsruhe, Germany. His main work area is RWT, the RAP SWT implementation, especially topics related to UI styling and theming.
I'm especially interested in the declarative UI and CSS styling features of e4. In RAP, we implemented a CSS theming subsystem and we would love to see a convergence between the RWT theming and the CSS support in e4.
I also mentored the implementation of a [[RAP_Theme_Editor|theme editor for RAP] as a GSoC project. This editor might also provide a good basis for CSS tooling in the platform.
