English speaking lessons

I am not a native English speaker, but I have spoken and worked in English all my life. I am 56 years old and reside in Berlin. Originally, I am from Sri Lanka and began my traveling experience in Hong Kong in 1991. Since then, I have been living and working in different countries. My area of expertise is business management, and for the last 25+ years, I have been working in both English and Portuguese. I have extensive knowledge of the language.
