  • Andrew Makin came on to support our ACE application in the beginning of the year and has been absolutely phenomenal, first picking up and understanding the Special Bids Business Process this application supports, and then working with other IBM application developer's to enable our new application, ACE2, to have the ability to inherit data and create work queue's for those responsible for action.

  • Thanks to you and Andy for such a really good job. I’ve had a few websites produced for my businesses in the past, but you both have been the most attentive, obliging and professional company to work with of all of them. In consequence I would have no hesitation in recommending you.
