Intro
I am a developer with over 7 years of experience. I mainly work on NodeJS. I have a lot of experience
with PHP. I was developing a microservice in Golang. In my spare time I am doing pet projects like RPC
framework or micro operation system, reading tech articles about methods of application scaling for
example. I am currently interested in creating an operating system. At work, I am always happy to take
part in the discussion of decisions and feel responsible for the project. For me, the project's success
depends on the organization of processes, the meaningfulness of technical solutions, and a pinch of good
UX.
