Fluent Level of English language. English teacher in a Brazilian boarding school

I have been living in English since 2016, but my interest on the English language did not start at that time. I was born in Brazil, Sao Paulo and I used to teach English for the High School classes of a boarding School I was studying, all of the students only could speak Portuguese. Since I arrived in the UK I have been put to speak English due to studies and jobs I had, and that made me fluent on the language and how to live the day to day as an English speaker. So I have plenty of experience on how reality is for foreigners to speak English on their work, and their daily routines. Nowadays, I am a part- time English/theory driving test teacher. I help speakers of other languages to pass on their theory test in the UK ( The test is only in English) , to get their well deserved driving license. In my classes you will have a non-judgemental teacher, because I was once on your side. We will break the ice and your shyness to speak English, regardless of your original language. You will learn grammar and how to speak, write and listen.
