Sergey is a super professional in playing the piano and in writing arrangements; in our case, it was classical music. He creates magical compositions in harmony, delves into the task at hand, and then decorates the foundation of the arrangement with the most vibrant colors. What was in the portfolio didn't quite suit us and didn't resemble what we wanted. But when he did a short test for us for free based on our notes, we were blown away by what we heard. Thank you very much for the work done; we will recommend him to everyone. Top level.
