I have very good command over English both in American and British. I can proof-read the documents, maintain 100% quality as per the guidelines from client, rephrase the sentences as per the situation, and find grammatical mistakes. I am an advanced user of Microsoft Word and I know very well the techniques of setting up language, spelling and grammar, thesaurus, track changes and so on. Other than Microsoft custom dictionaries, I am using Oxford online dictionary and WordWeb Pro dictionary to find out spelling errors and idioms.
