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).
