You can also contact us for help with programming.

Drupal modules:

  • Development of new modules
  • Modification, extension or porting of existing modules

Resolve errors. If an error occurs that is not resolved quickly enough, you can contact us.

  • In Drupal core
  • In expansion modules

We prefer to work in such a way that the results can also be given back to the Drupal community. The advantage to you is that your website can be easily updated. Also, others can continue to build on your adjustments which can also be in your advantage. We will state you as the sponsor of the module or of the changes.


  • Modules which are being maintained by Buro RaDer: Availability Calendars and ImageCache Actions
  • Modification of existing modules: Squeeze
  • Writing of patches for Drupal core or extension modules: see the posts of fietserwin.
