Maria Belen Quis focused on enhancing the database schema for the Dauphinsss/Redibo-Backend repository, delivering targeted improvements to the insurance domain models. She addressed schema clarity by renaming key attributes, such as changing 'enlace' to 'enlaceSeguro' in SeguroCarro and 'valides' to 'cantidadCobertura' in tiposeguro, and updated the associated migration scripts to ensure consistency. Using Prisma and SQL, Maria applied disciplined refactoring and schema management practices, reducing ambiguity and risk during future migrations. Her work established a clearer, more maintainable data model, providing a stronger foundation for upcoming insurance features and supporting cross-model consistency within the backend system.
