Fluent and exceptional mastery of the English language, and specific aptitude for perfection concerning anything related to the language allows me to finely scrutinize every single detail in any document or written form of English and weed out even the most minor and elusive flaws in such work. Furthermore, my expansive familiarity with the language's vast lexicon allows me to not only proof-read for mistakes, be they grammatical, contextual or even semantic, but to come up with contextually-compatible synonyms and advanced restructuring of any written piece of work to make it appear more formal, complex, or simplified, depending on the kind of document and its purpose.
