I frequently develop and test open source web application.
Here are a few that I’m working on:
Drupal6 [http://peterchuang.com/drupal]No longer online.
I’m building an integrated event registration site for the Office of Professional and Community Education at the UCLA Semel Institute. Drupal6 and CiviCRM seem to provide the best mix of architecture, feature, configurability, and clean code. There are areas that I still would need to tackle, especially the payment processing portion. I need to write a custom module for that.
Joomla [http://peterchuang.com/joomla] and [http://asnbiz.com]No longer online. SugarCRM [http://peterchuang.com/sugarce]No longer online.
