Im a consultant with experience from many large companies and organisations in sweden. I have worked with a lot of CMS systems and I must say Drupal beats them all! My fist Drupal project was in 2007, but I have played around with Drupal since 2005.
I'm a Drupal core developer, and a member of the security team. As well as code I have also contributed to the project with design work, documentation, accessibility and usability improvements.
I'm also one of the organisers of the many Drupal events we've held in London for the last 5 years.
