    “It was a complete pleasure working with Sergey. We instantly established clear communication of the projects goals and expectations which in the end resulted in a flawless delivery. Sergey really put great care into delivering the project, with regular updates and feedback/questions if something was unlcear. This is the sort of attitude that I'd expect from every expert freelancer. Sergey definately is one of them! 100% would rehire. Thank you.”
