Rukaya AI
A native-like, zero-network offline Progressive Web Application (PWA) and AI spiritual companion.
Production Metrics & KPIs
Validated System Telemetry
Problem Statement & Scope
The Architectural Vector
Engineered Rukaya AI into a resilient, native-like mobile web application operating on a "True Offline" architecture. Leveraging Service Workers and IndexedDB client caching, the system provides zero-network availability for prayer timetables, an offline AI conversation loop, and haptic-responsive counter tools.
3 Deep Technical Challenges Overcome
Architecting a robust cache-first Service Worker lifecycle ensuring seamless operation during total offline state.
High-precision solar prayer time mathematical calculations running client-side with zero battery drain.
Simulating native mobile gesture responsiveness and vibration feedback on both iOS Safari and Android Chrome.
System Design Breakdown
Architecture Specifications & Hardware Primitives
IndexedDB offline persistent store + React 19 Client hooks
