Простой открытый человек, живо интересуюсь ИТ технологиями: JVM based languages, различные платформы виртуализации, оркестрации, NFV, SDDC, интернет сервисы, БД, архитектура различных ОС, архитектура процессоров. Ну и микроконтроллеры Arduino, STM32.
Сейчас развиваю в свободное от работы время свои проекты. А еще очень люблю просто гулять по городу.
