Answer 3

Good afternoon!
Go to the programmer - mobile development, web applications. And deepen system administration in the plane - to programmers - devops, build systems, web servers, databases, application virtualization systems, etc.
Otherwise, you can work with Enikey all your life - it's boring, and there will be little time for development (although where it is), IMHO, programmers get paid more... :)
