Hello,
I am a Brazilian Portuguese native speaker & freelance translator with over 15 years experience translating all kinds of stuff from English & Spanish into Brazilian Portuguese. Tutorials, softwares & hardware manuals, books, app websites, webpages in general, apps, games, and so forth.
Also, as one significant project here on this site, I would like to mention that I was invited by Freelancer.com administrators and took part in the translation team for their Brazilian Portuguese official website version.
Unfortunately, I could not bid accordingly as my translations are based on word counting (as well as deadline). My per word rate is US$ 0,022.
I would be happy to collaborate on your project.
I look forward to hearing from you
Cheers
Maria Thereza
