I'm Brazilian, and I work as a consultant for an Information Technology company. I use to travel a lot inside Brazil, but not very often outside it. This is fairly a new job to me, and I'm enjoying it a lot.
I formally studied English for something like 4 to 5 years, but this was a long, long time ago. I haven't been practicing my listening and speaking skills since then, and I seldomly practiced writing, even though I had been reading a lot in English more recently.
So, I was very please to find italki.com, because now I can practice my speaking and listening skills in a way that fits my traveling needs.
