Finding good Scala devs is a real quest because these specialists are not so frequent nowadays. As they are in short supply, the hourly rate can rise up to $60 per hour of an experienced Scala developer. This happens because the Scala programming language is mostly learned by developers who have already experience in Java. They gain this additional skill to build systems more effectively, that’s why the rates may be higher compared to other languages. Other factors that influence the development cost are the complexity of the solution and the scope of the project.
