Aiyush Dhar worked on stabilizing the expense form in the fylein/fyle-mobile-app repository, focusing on resolving a bug that affected the rendering of custom fields during add and edit expense flows. Using TypeScript and leveraging front-end and mobile development skills, Aiyush ensured the correct category value was consistently passed to the getCategoryOnAdd and getCategoryOnEdit functions. This technical approach improved the reliability of custom field rendering, reduced user friction, and enhanced data integrity for expense reporting. The work clarified category propagation logic, contributing to the maintainability of the codebase and supporting a smoother user experience in expense management.
