Pierrejeanlievens
Pierre-Jean Lievens refactored the quiz data model for the hfreshnel/Spring-Project, introducing new Question and Proposition entities to support more flexible quiz structures. He redesigned entity relationships, added fields for question text and correctness, and decoupled associations to improve maintainability. Leveraging Java, Spring Boot, and JPA/Hibernate, Pierre-Jean also implemented non-persistent Data Transfer Objects to enable analytics and leaderboard features. He configured a local MySQL development environment, streamlining testing and collaboration. His work included targeted code cleanup and class reorganization, addressing technical debt and laying a foundation for scalable backend features within a well-structured codebase.
