While I do not live in USA / the UK,I have Avery good command over English. I am a native English speaker. I have written,, edited and proofread a number of articles, business plans, research articles etc. Owing to my MBA degree & also due to the fact that I have worked in a corporate job for years, I am not a stranger to any sort of business communications, be it business plans or emails/ reports. My certifications on freelancer include English(UK &US both) and academic writing.
I am also very much at home using MS office tools. Excel is my forte and I can easily analyse data using the various formulas and functions available there in.
I always strive to finish the work before the stipulated deadline. I have recently done a similar job for someone based in the UK
