Preparing my presentation

I'm going to become a Russian teacher on italki but my English is not so good and I'm not sure if my presentation is correct.
My name is Tatiana and I am from Novosibirsk, Russia. Russian is my native language. My university degree is in Russian language and literature. Also, I have an additional education in teaching Russian as a foreign language. I am also at an advanced level of Italian, an intermediate level of English, and I have just started to study Portuguese. Since I'm a language learner too, I understand the difficulties you may face at each stage of studying a foreign language. If you want to improve your Russian or you just want to start learning it, feel free to contact me and we’ll see how I can help you.

:-) Nice introduction! -Pat
