Home reveals qualities that are not always visible in an official biography: patience, respect for elders, care for close people and the ability to be present without loud words.
Responsibility at work begins with a person’s inner structure. When actions, words and attitude to people coincide, this is visible both in profession and in family.
For some colleagues he was Uncle Kostya - not because of a position, but because of a human feeling. They could come to him for a practical hint, calm advice or a simple conversation when clarity was needed.
This part of the story matters as much as official titles. It shows why people around him understood how to act, whom to rely on and whom to ask when they needed a precise answer.

In family and work the same quality was visible: when there was a task near him, he did not step away from it - he helped bring it to a clear result.
