Featured Projects
A selection of products I've designed, built, and shipped — from AI research tools to multi-cloud infrastructure.
Alhajj-Platform
A multi-tenant SaaS for end-to-end Hajj pilgrimage management — real-time pilgrim tracking, geofenced safety alerts, AI-based health-risk inference, and a built-in RAG assistant.
- NestJS
- Next.js
- Capacitor
- MongoDB
- Redis
- BullMQ
- Socket.IO
