I'm on stackexchange because of two things: C++ and Japanese. I'm an intermediate/middle C++ dev and an active Japanese learner (I'm not even an N5 yet though) who wants to learn the language as fast and as effectively as possible.
I'm Ukrainian myself, my native languages are Ukrainian and Russian. Fluent in English (C1/C2), actively studying Japanese (pre-N5). Don't hesitate to get in touch if I could be helpful to you in any way.
