There he entered the second grade at experimental School No. 255, which specialized in mathematics and programming. Programming was taught from the second grade to children with good mathematics grades. One day, a teacher asked him to stay after class and told him he would be moved to another class. Pupils from different classes were being brought together to train as future programmers.
In 1987, he began studying programming at school. The pupils learned BASIC, Fortran, Pascal and Algorithm.
At the same age, he became interested in amateur radio and electronics, building circuits and repairing equipment, including third-generation semiconductor televisions.
Electronics was his hobby at home. He assembled and repaired equipment at home, studied programming at school and attended sports clubs after school: first freestyle wrestling and judo, then karate.
