I am a Masters in Project Management Degree Graduate from Kenya.
Our country's education system is English based and official Business language is English.
I have made some books publications on Amazon (Search Author - Daniel Olala), to confirm.
Currently I live in Bochum and am free to take up teaching lessons to impart my language skills in the best way I know to improve on anyone wishing to get the knowledge from me as I personally learn German language along the way.
