Christian is a great developer who produces elegant solutions to tricky problems. He's great to work with, always happy to share his knowledge, and has been pro-active in shaping and improving our applications. A great guy and a valued team member.

Christian is a very skilled and intelligent web developer, with excellent communication skills Having worked with Christian for 18 months at Good Things Foundation, I am able to highly recommend him as a talented and resourceful developer, who is keen to learn and develop both himself and those around him. Christian is unafraid to rise to new challenges and in doing so find new ways to meet those challenges. He is happy to investigate and use new technologies, including frameworks, in order to deliver the task in hand to the best of his abilities. In learning new technologies Christian not only learns how to utilise them, but he will also discover how they work. This enables him to fully leverage the functionalities that these technologies offer. Christian has a firm grasp of many of the more abstract concepts that lay behind development. Concepts such as object orientation and separation of concerns are very familiar to Christian and he is keen to implement these abstract ideas in his code. This enables him to develop code that is scalable, maintainable and thus robust. Christian is an amiable person and this makes him a great team member. He is happy to discuss things that he has learnt with fellow developers, sharing his knowledge and findings. In his dealings with the wider business, Christian is approachable and confident.
