I am more than pleased with our experience with Viacheslav. The professionalism and honesty I received was a breath of fresh air. Getting to work with him and making him part of the team was extremely valuable. I knew after discussing my project with him that he was the candidate I wanted. I hired him immediately and he wasted no time in getting to my project, even going the extra mile by adding some great design elements that enhanced our overall look. His knowledge of developing and writing smart contracts was extremely impressive.
