It was great to work with Sergei. His professional design solutions have positively affected the product and business in general. He demonstrated exceptional skills as a design-system lead dealing with complexity and the necessity to communicate with multiple stakeholders. Sergei's solutions were logical and supported by arguments.
Sergei and I worked together on the same team at MyOffice. As a senior product designer Sergei always considers several solutions and reasonably offers the best of them. As the leader of the design system direction in the company, Sergei has shown that he is able to solve complex problems and make things done. I recommend Sergei as a strong designer and responsible employee.
Sergei did an excellent job. Developed the UX and then the UI of the application. It was a completely new app design. After redesigning our music app, NSM increased by 30%
