Right, you think that Node.js is a terrible platform for you. I'm pretty sure that everyone here would agree with that statement. You really can't make any more general of a statement than that though given your limited experience.

I actually would advice that it's bad in general, not just for me.

If node.js works for you, then I'd argue that Go would work even better for you.

If you don't mind losing some of the expressiveness of python/ruby, then surely you wouldn't mind transitioning from python/ruby to Go. And, what's more, Go is much better suited for large and complex programs than Node.js.
