In LanaLabs (located in Berlin) we were developing the process mining solution and it was incredible. The code was so clean, very nice architecture and I was glad to work for them. Unfortunately, I decided to come back to Ukraine.

I expect to be part of the nice team with nice designed processes and fast developing culture. Would be cool to develop something important for human (in general), environment, disables etc. I have an interested in golang, would be cool to develop something on it, no experience there tho (but its just a language).

At this moment my job is to develop sql-scripts for Mysql. Also I write some scripts in Python which send and get some data with rest api and json api. As for my hobby, my passion, so I like Java and jvm stack for 5 years, have been doing some little projects. One commercial project are done and used in a real company now. Then I found myself in Scala programming language and I like it much more than java now. I try to write programs not only in OOP style but much more prefer functional style and benefits of it.
