We're building Websites and Desktop Applications. Websites in SilverStripe or Zend Framework, Desktop Apps in PyQt.
Since almost 10 years we're building websites, since 5 years desktop applications.
We have experiences from big-traffic sites to desktop application for sophisticated energy-calculations and photovoltaic analysis.
Our web-site isn't ready right now. This is caused by the too many orders we have to work off right now.
