Nick Abbott is a full time Drupal Web Development Consultant / Trainer, and Open Source evangelist.

Trained as an Applied Physicist in the mid-1980s, Nick began his teaching career in 1989, and after many years in IT in the independent education sector he moved full time into the commercial web industry in the Autumn of 2008 to focus exclusively on Drupal, and in particular, Drupal Commerce.

As a staunch advocate of Open Source community-driven projects, Nick promotes investment in people, systemization, training, and support over expenditure on software per se.

He currently provides training through i-KOS Digital Services, a London-based Drupal Commerce specialist.
