    “I found Sergej R. very professional in his attitude towards my job. Firstly he was the only one who read my posting and responded with a detailed bid submission. Everybody else was a quick and dirty copy and paste reply, that shows a great attention to detail. He was very knowledgable on the task and was able accomodate the task to my budget, and all correspondence with him was clear and concise. It was a difficult job from the point of dealing with somebody elses code compiling for me but he rose to the challenge and was able to compile the project and also create an additional guide on how to duplicate which is not something I originally asked for. The work was done in a timely fashion and I got exactly what I needed and more. If you are reading this and considering him for your task I would most definitely reccomend him.”
