Developed the foundation of the Flights Management Module for the Monarca_Backend repository, focusing on backend architecture and robust data modeling. The work centered on expanding the Flight entity to include duration, supporting reliable management of flight data and enabling future integration with scheduling and booking systems. Leveraging TypeScript, NestJS, and TypeORM, the developer established core entities and incremental backend features, ensuring the groundwork for end-to-end flight workflows. The approach emphasized disciplined version control and clear documentation of module initialization and entity enhancements, resulting in a scalable backend structure designed for extensibility and seamless integration with analytics and related modules.
