PROFILE
Matthew Dang
Matthew Dang developed and enhanced core features for the lichess-org/mobile repository over a three-month period, focusing on user experience and maintainability. He built a robust puzzle hint system, introducing a new hint button, real-time solution highlighting, and improved move visualization, all implemented using Dart and Flutter. To ensure long-term code quality, he refactored and standardized UI theming through a centralized color management system, unifying color usage across puzzle analysis, game views, and performance statistics. His work emphasized code cleanup, formatting, and state management, resulting in a more consistent, accessible, and maintainable mobile application aligned with modern design principles.
