Ajay Liu developed the foundational Student Domain for the ucsb-cs156-f24/proj-happycows-f24-10 repository, focusing on backend architecture using Java, Spring Boot, and JPA. He designed a new Student entity and implemented a dedicated StudentRepository, enabling efficient queries by id, email, course, and permission. Ajay aligned the database schema by renaming the table for consistency and standardized repository return types to Iterable, simplifying the API and improving maintainability. He also created a Student.json migration file to support schema evolution. The work established a robust, extensible data model, laying the groundwork for scalable student data access and future domain-driven features.
