December 2025 (2025-12) focused on establishing the foundation of the data layer in data-hydenv/data. Key delivery: Core Data Models and Project Scaffolding with initial files added to establish the core data structures and repository organization. Commits 5720eddb289a214c71a9c8d0bb40ac3075fff3f3 and 49a06506609a3078a3f32af7c683f47442ce8666 captured the foundational work. No major bugs reported or fixed this month; work prioritized architecture, maintainability, and long-term velocity. Key achievements for the month: - Set up initial data models and repository scaffolding to enable consistent data structures and scalable development. - Introduced foundational files and project structure that support future data features and pipelines. - Laid groundwork for onboarding new contributors with a clear, modular data layer. Overall impact: - Provides a solid foundation for data-related features, reduces future rework, and accelerates downstream feature development. - Improves data integrity through centralized models and standardized scaffolding. Technologies/skills demonstrated: - Data modeling, repository design, and project scaffolding - Version control discipline with multiple commits establishing foundational assets - Ability to translate business needs into a scalable data architecture
