I am kind of/sort of an introvert person

[Rachel Adams]

What would be a more formal way saying "I am kind of/sort of" and isn't it wrong to use "to" in this context?

"I am kind of an introvert person. Spending time alone isn't a problem for me."

Don't use "introvert person". Use either "an introvert" or "an introverted person". You could say "I'm quite/fairly introverted".
I don't understand the second part of the question. You haven't used "to" anywhere in your sentences.

I mean "spending time alone isn't a problem to me". Is it wrong to use "to"? And aren't "sort of" and "kind of" informal?

I would probably use "for' there, but I think "to'" works also.

Yes, they are informal usage.

What would be used instead in a formal language?
