- Webhook Handler: Validate and update order statuses through webhook callbacks.
- Admin Dashboard: Monitor orders and payment statuses with filter/search capabilities.
- API Integration Layer: Service layer to interact with the UPI API provider.

Tech Stack:
- Backend: Django, DRF if needed
- Frontend: Django templates with jQuery or standard HTML/CSS/JS
- Database: PostgreSQL or your preference
- Deployment: Docker on AWS/GCP/Heroku
- Security: HTTPS, webhook signature validation, secure key management

The project needs to be completed ASAP. Ideal candidates should have:
- Strong experience with Django and webhooks
