Worked on enhancing the EngineLines UI in the lichess-org/mobile repository, focusing on improving scalability and accessibility for users with varying font size preferences. Addressed layout rigidity by refactoring the widget structure, replacing a fixed-height SizedBox with a ConstrainedBox to enforce a minimum height while allowing for larger, scalable fonts. This approach preserved the baseline layout and ensured resilience to font-size changes, directly supporting accessibility goals. Demonstrated proficiency in Dart and Flutter, particularly in responsive UI development and layout management. The work was delivered as an isolated, low-risk feature with clear documentation, contributing to maintainability and traceability within the codebase.
