Nov 1, 2025November 2025 performance and data integrity improvements for leihs-inventory. Delivered two key features: (1) Image caching and retrieval enhancements, adding cache-control headers for images and thumbnails (30-day max-age) and refining retrieval to ensure correct associations with models and categories, boosting API performance and accuracy; (2) Updated the database subproject reference to a new commit to align database structure and content across deployments. No major bugs fixed this month; focus remained on performance, reliability, and maintainability. Overall impact: faster image delivery, more reliable APIs, and a cleaner, more maintainable codebase, supporting scalable inventory operations. Technologies demonstrated: HTTP caching strategies, image retrieval refinement, database subproject coordination, and disciplined commit hygiene (chore-level changes).
