Hi!
I would love to help you out. I am a native English speaker, and I have studied both American and British English. I grew up in an international school with American friends, and graduated in English Higher Level from the International Baccalaureate. I then went to college in Boston, USA, so I am as good in speech as I am in writing. I am very good in grammar and can catch any mistake. I can also rephrase sentences to make them sound more native.
I hope we will be able to work together!
Best,
Nina
