“Talking about Jesper I can say that it has been a pleasure and honor to closely work with one of the very few guys in the real top league of software development in the past year. It is very though to list all the good skills Jesper has because these are just too many. He is one of the smartest, prepared and qualified person in the field of IT I have met in my career, which is not surprising if you just look around a bit in internet as he does not even need any introduction. He is able to constantly produce very high quality code even under very tight deadlines, keeping always the right balance between quality and getting things done on time. Apart from his technical skills his soft skills are excellent, as he manages to always keep calm and maintain good atmosphere even under periods of high pressure, and very easily keep people in sync. For all of this and much more I do not only recommend Jesper but would definitely enjoy working with him again. ”
