During September 2025, Sonia enhanced language settings documentation for Expensify/App and callstack-internal/Expensify-App, focusing on clarity and accuracy for multilingual users. She updated Account-Settings.md using Markdown, refining instructions for changing language preferences and ensuring current language support was clearly represented, including the addition of Chinese (Simplified). Sonia’s work involved careful version control and cross-repository alignment, reducing ambiguity and improving onboarding and self-service for users. By fixing typographical errors and streamlining documentation, she demonstrated disciplined documentation practices. The depth of her contributions lay in precise, traceable updates that improved user guidance and reduced potential support issues across both repositories.
