<p>Architected an event-driven backend decoupling heavy health-record ingestion (Malaria, Finance, Immunization modules) into independent RabbitMQ worker services, enabling horizontal scaling per domain.<br>
Engineered hierarchy-aware aggregation algorithms to eliminate hierarchical double-counting across millions of health records, resolving critical reporting discrepancies for government stakeholders.<br>
Built an interactive analytics frontend with react-leaflet geospatial maps and Recharts dashboards, enabling LGA-level data-driven decision-making.<br>
Implemented aggressive Redis caching + WebSocket push to deliver real-time dashboard updates without overloading primary databases.</p>
<p>Built an offline-first PWA from scratch using Serwist service workers, enabling healthcare workers to operate fully in zero-connectivity environments.<br>
Designed a background sync engine with a custom OFFLINE_QUEUE_SUCCESS request queue to capture offline mutations and replay them reliably on network restore.<br>
Built a local merge strategy combining cached IndexedDB data with fresh API responses and 'shadow records' for instant optimistic UI feedback, drastically reducing perceived latency.</p>
