Tourists visiting Egypt lack a reliable, offline-capable digital guide that contextualizes historical landmarks with multilingual support and route planning.
Built a cross-platform Android app and companion website that aggregates cultural landmarks with rich media, interactive maps, and on-device navigation using Google Maps SDK.
- Architected the Android app with MVVM pattern and Room database for offline access
- Implemented Google Maps SDK integration with custom landmark overlays
- Built the companion website with React and deployed via GitHub Pages
- Integrated multilingual content system supporting Arabic and English
