Sergey is a sharp, persistent, proficient developer who is indeed a database expert with excellent analytical skills. He takes the initiative (without having to be asked/advised) to thoroughly investigate and resolve issues without taking shortcuts or being lazy (e.g. he created over 10 different user accounts to test his work). A quick learner who doesn’t require babysitting, nor wastes time. A+ rating.
