Nikolay worked professionally with a complex database provided by Yota and built a well-structured reporting system for our department. The data prepared by Nikolay helped our Customer Experience department to evaluate post-campaign results more efficiently. His careful attention to numbers, diligence, and thorough approach to analysis always helped to take in the situation and gain insights in a short time. I would highly suggest working with him!
