FundFinder Cameroon's sequence diagram orchestrates a multi-layer grant discovery platform where WordPress CMS serves as the central hub connecting NGO users, mobile clients, and external grant portals. The architecture flows through six phases: initial page requests, mobile access, grant browsing, detailed grant views, and external portal redirects—all managed via WordPress post types, custom fields, and external link handlers. This design demonstrates how a lightweight CMS can aggregate fragmented grant opportunities from multiple sources (Grant Portal A, Grant Portal B, Donor Website) without direct data synchronization, reducing maintenance overhead. Fork this diagram on Diagrams.so to customize grant categories, add authentication layers, or integrate additional donor networks for your regional nonprofit ecosystem. The sequence prioritizes user experience by separating presentation, application, and external service layers while keeping WordPress as the single source of truth for grant metadata.
