Summary

Full-stack software engineer with 12+ years of experience.

I am mostly excited about functional programming both on the client and server side. I like Scala and its ecosystem (ZIO, Cats, Shapeless, Akka, Slick, Doobie, etc.); in addition, I have good problems solving and projects responsibility skills. I am studying and evolving every day to provide actual and high-level results to the customer; actually, I follow T-shaped skills model: besides Scala and its environment I am also keeping up in JavaScript / Node.js trends therefore I can start working with them pretty quickly. I read news, listen podcasts and watch videos about different technologies to have wide area of thought (Perl, PHP, Python, Rust). I am free to use Linux, Mac OS or Windows and ready to work with Git, AWS, Jenkins, Circle, Bugzilla, Redmine, Jira, Bamboo, Trello, GitHub, BitBucket and other commonly used services.
