Andres Oide developed the foundation for the Flights Management Module in the Monarca_Backend repository, focusing on backend architecture and robust data modeling. He expanded the core Flight entity to include duration, enabling more comprehensive flight data management and supporting future integrations with scheduling and booking systems. Using TypeScript with NestJS and TypeORM, Andres designed the initial module structure and implemented disciplined version control through incremental commits. His work established a scalable groundwork for end-to-end flight workflows, prioritizing maintainability and extensibility. Over the course of the month, he concentrated on backend development and database design, delivering a foundational feature set.
