I'm also developer and I know how other niches can help new apps or games. Brazilians really like games, and they hate when they can't understand what they are reading.
I can guarantee high quality and specially well-localized texts for any game-related translations.
I can also post a review on my blog with 5~8k visitors daily (extra gig). And I can also translate other kinds of text (like complete list of strings), just order my extra gig.
Feel free to contact me if you have any questions!
