Mar 1, 2025March 2025: Achieved end-to-end domain scaffolding and MVC wiring for HexaStay, establishing a scalable foundation for feature delivery. Key features delivered include: (1) Initial project scaffolding and core domain components (SampleRepository, SampleService, SampleServiceImpl) with logging; (2) Layer wiring that connects controller, DTOs, HTML, and service layers to enable a working feature flow; (3) Database migration from H2 to MariaDB across the project for production-grade persistence; (4) Entity scaffolding with BaseEntity and date handling improvements; creation of the Repository module and Entity DTO Repository; and continued Batch 3 scaffolding/baseline updates; (5) Additional scaffolding work for entity files with placeholders. Major bug fix: union keyword handling fixes to avoid reserved-word conflicts across multiple commits. Overall impact: accelerated development velocity with a stable and scalable domain/data layer, a reliable MariaDB-backed persistence layer, and a clear path for future features. Technologies/skills demonstrated: Java, layered architecture (controller/DTO/service/repository), JPA/Hibernate concepts, MariaDB/H2 migrations, Lombok (Log4j2), DTOs, and repository-based data access.
