I have been working with Denis for approximately 1.5 years now and I must say his knowledge, skills, and abilities are leaps and bounds ahead of other developers I have worked with in the past. He is proficient in full stack development for both desktop and mobile. During this relationship, we did have one misunderstanding, but we were able to discuss it in-depth so that way we could be on the same page leading to a successful relationship. It is my goal to continue to work with Denis for years to come.
