Developed the backend foundation for the Competition Service in the bettercodepaul/swt2-bsa-backend repository, establishing a Spring Boot skeleton to support future user-facing features. Focused on creating robust error handling and defining data transfer objects for core entities, the work improved the architecture’s maintainability and scalability. Integrated Maven-based build and test workflows to streamline continuous integration and delivery, enabling faster iteration cycles. Standardized constant naming conventions to enhance code quality and consistency. By laying the groundwork for competition classes, configurations, and download capabilities, the project accelerated the development of related features and ensured a reliable base for ongoing REST API development.
