English class, intermediate level B1 to B2

Good Morning
My name is Mariana Giraldo,I am a 21-year-old Colombian living in Rennes, France to conduct an M.Sc. in Strategic and Digital Marketing. I have a degree in Management Engineering. Furthermore, I am fluent in Spanish and advanced in English, as my classes in France are conducted in English. Although, I am trying to improve my French by taking classes.
I'm interested in giving English classes, as it's a language that I have learned since I was little, so it is easier for me to teach as I was in the student position once.
