I would like to acknowledge the excellent collaboration and cooperation with our IT team particularly on the recently completed rewrite of our eDealing application front-end. Despite several challenges and a very aggressive project schedule, the team worked well together and took extraordinary steps to complete the project on-time. The project team also provided superb hyper-support during the go-live period to minimize as much as possible the impact to our user community for eDealing during the upgrade.We value 300 Brains as a reliable technology and business partner.
