Please, proofread a few lines of text

Hello.

My written English is at upper intermediate level as the result of having more than 4 years experience communicating with foreign colleagues in writing.

What do you think of that? Can you see any grammatical mistakes (the highlighted part bothers me the most) ?
If you would suggest your refinement of the text I would be more than happy.

Thanks, Alex.

I would use "as a result" rather than "as the result", otherwise it's fine.
