Dear MoonlightingSA, I'm a native Portuguese speaker, I have a Master Degree in Languages, Literature and Cultures, and a professional training in IT as well as a vast experience as a translator (websites, legal and technical documents, articles, eBooks, books, you name it). Being mandatory to be an impeccable proofreader too, I can give you a flawless translation of your 3375 words about words and sentences used in mobile applications, from English into Brazilian Portuguese, with high quality.
