[Shawn] understood exactly what was needed and made very thoughtfull and useful suggestions for the site’s usability. The evaluation of the site received excellent feedback from its users. In his work, Dr Koppenhoefer has proved to be a reliable, creative, enthusiastic and well organized colleague. I highly recommend him for his programming skills, as well as system administration and teaching capacities.

His keen eye for a good user interface, sensibility to peoples needs and skills, and sixth sense for how people think, made the development process efficient. He is capable of getting the job done, especially if it involves HTML, JavaScript, and PHP.
