What our previous clients said about us!

Chris stepped into a difficult project and was able to take a complex set of requirements and deliver on them with excellence. Working to customize the open-source Moodle platform, Chris showed great programming ability. Over the many months of the project Chris had to work independently and solve challenging problems. He asked great questions and brought new ideas to the project that improved the final product immensely. He’s a great communicator and is able to think holistically to build smart solutions. I’d work with him again in a heartbeat.
