Hi! I am Nikita and I am backend developer from Russia. I am working as a Software engineer for 3 years now. My usual tech stack is Java (sometimes Kotlin), Spring framework, Hibernate, Postgresql, and also I use Python a little. I also try to participate in an opensource by contributing to project like CreateDB and ElasticSearch I want to find some community to share opinions and discuss different tech stuff, so feel free to keep in touch with me!
