🏆 Two Revolutionary Architectures. One Powerful System.
Template Method Pattern (85% code reduction) + Event-Sourcing (timeline intelligence) = The most advanced orchid management platform ever built.
OrchidPro is a cutting-edge .NET MAUI application that reimagines orchid collection management through two complementary revolutionary systems:
- 🗂️ Botanical Taxonomy Module - 600+ pre-loaded species with Template Method architecture
- 🌱 Personal Collection Module - Event-Sourced timeline with predictive intelligence
OrchidPro combines TWO groundbreaking patterns that work together seamlessly:
Traditional CRUD: OrchidPro Template Method:
