Private lessons in English or Math or German (speaking)

I am currently living in Istanbul and would like to give private lessons in English or Math. German speaking lessons would also be an option. I am fluent in both English and German and have a Bachelor degree in Mechanical Engineering. In university I did private tutoring for 2 years and the last 3 months I have been tutoring English and Math full time. I can tutor all ages from 8 upwards. I really enjoy teaching and am very dedicated to structuring the lessons in a way that my student learns as much as possible, but most importantly also has a good time doing it!
