Hi,
English is not my main language, but that's no hinder for me. I've learned it in school from a young age and throughout my childhood I was constantly exposed to it with English TV shows, movies, video games, online friends etc. etc.
I've even lived abroad in Malta, an English speaking country, for 3 years and there I of course spoke it on a daily basis.
I know my way around the English language, and I'll perform to the standard you expect.
