Hi Aakiwowo
Welcome to Switzerland and the forum.
It's great you are enjoying getting to know this truly beautiful country and learning German as that will definitely add to and enhance your experience of living here.
I can't make any recommendations regarding a private German tutor but ran a quick search on the forum and came across this
EF member located in Zurich and Basel,
who offers German and Swiss German conversation lessons to clients*.
You can also do a more extensive search for yourself through the
Jobs wanted section of the forum for others offering the same service.
Hope that helps and good luck!
