Dear madam/sir,
Hello, I am a native Japanese translator based in Amsterdam, experienced in app translation and localization. I currently freelance with a company called Appury, which translate and localize apps and games to launch for Japanese audience. I think I can very well contribute you to this project in a professional way. I can work with different formants such as xml, I'm able to translate out of "strings" as well. I'm very familiar with QA process regarding this type of project, I can assure you I provide you with a quality translated-localized material. I am also a certified English teacher, you can count on my English=Japanese skills.
Very much looking forward to working with you.
Best regards,
Waka
