junior Scala developer

Remote work, Russia · $600 · Less than a year of experience · Upper Intermediate

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.
