Cocoon user with special interest in XML and XSLT.
I have my own company named Xangeli, where I'm developing a complete system for managing small companies. The system is available online, on my own servers, and users can subscribe to the services they need for their company.
The core of my system is Cocoon, where i develop all my business logic. For storage I use MS SQL with SQLXML, and Apache Httpd as proxy.
