I'm happy where I am right now, but everything is possible for the right price.
In the past I worked on projects in different domains using different technologies including java, node.js, php, python, so picking up a new language won't be a problem.
In the future I want the main focus to stay with functional paradigm: scala, rust, closure, etc. Switching to managing positions is also an open option for me.
