Hossam Saleh developed foundational data persistence features for the PlanMate repository, focusing on durable state management and maintainability. He implemented a CSV-based state data persistence layer using Kotlin, applying layered architecture and the repository pattern to enable CRUD operations and facilitate future testing. By renaming the ChangeHistory entity to ModificationLog across data sources, mappers, and tests, he improved semantic clarity and code maintainability. Hossam also established initial project documentation, outlining the data architecture to support onboarding and knowledge transfer. His work demonstrated depth in data modeling, file I/O, and test-driven development, laying groundwork for future analytics and enhancements.
