Ask HN: Where can my IT-related articles be proofread and fact-checked?

I am going to begin writing articles to share my knowledge and demonstrate the expertise on my portfolio site as a frontend developer. I am not a native English speaker so my word can sound boring and dry, probably too formal in some cases or even just simply ugly. More than that, I would be happy to have someone from my domain who can read my articles, edit them, find erroneous facts or even wrong techniques.

So, in the end I want to turn my thoughts into clear form written in live language without ugly language constructions as well as checked for domain-related misconceptions, wrong assumptions, bad practices.

Are there any services focused on such things or should I find someone on my own like looking through tech writers blogs or by googling?

Please share your thoughts and experience.
