English with a South African living in Germany

I have a Masters Degree in Genetic Counselling. I worked in clinics and hospitals in Johannesburg, counselling patients about the risks of inherited conditions and testing options where applicable.
We then moved to Kenya for a year. Upon our return,
I worked for a Non-Profit Organisation (NGO), building and managing a team of about 30 call centre agents.
Before we left South Africa for Germany, I worked as a High School Biology teacher.
My experience also includes a few months of online lessons during Covid.
I have also completed a TESOL course for teaching English.
