I can teach basic and casual English. I have been an English language speaker for more than 20 years now. I used to work in a call center that caters to English speakers and I am working with an American company in congruence with this job as an ESL teacher. I have a blog wherein I post whatever articles I write, mostly in English. My English proficiency level is at C2 in the Common European Framework of Reference in Language(CEFR), this is equivalent to a CPE/IELTS band score of 9 or Test of English as a Foreign Language(TOEFL) score of 120.
