User Interface Localization to American English

I am looking to localize the text in our user interface to American English. The primary audience for this localization is adults (20-59) and so the localization must reflect the appropriate formality.

Key requirements:
- You will be responsible for translating all text within the user interface, this includes all buttons, pop-ups, error messages, and other on-screen text.
- The translation must be to formal American English that is suitable for adult users.

Skills and experience required:
- Proficiency in both the source language and American English
- Experience in localizing software user interfaces, especially to American English
- Understanding of the nuances of formality in language
- Strong attention to detail as the text must be accurately translated to ensure the user interface remains functional.
