English teaching, computer use and software development, science and maths help

I am English living in central Bruttany. I qualified from Cambridge university as a physics and general science teacher. I have spent 40 years working with computers, writing software. Thus I can teach and help with all of this either via internet or in person.
The only issue in France is that I am not bilingual yet so the lessons will be mainly in English though I can read questions that are in French in order to provide help with the answers.
Maths is also available because it underpins a lot of physics and computer software so I have a good deal of experience.
I am patient and my methods involve explanation, maybe in several different ways, demonstration and exercises for the pupil. You never learn without doing, and in fact I may well get you to explain it back to me, perhaps in French to help my learning there, a week or two after teaching you in order that you learn by teaching - a very effective method indeed.
