Döner App — Real-Time Restaurant Ordering Platform

The Döner App is a full-stack system modeling a real-world restaurant workflow end-to-end — from customer ordering to kitchen operations.

The backend follows Clean Architecture principles, ensuring strict separation of concerns and testability. Business logic is encapsulated within a domain-driven design, where orders act as aggregates with explicit state transitions.

Real-time communication via SignalR ensures both customer and admin applications stay fully synchronized without polling, providing a seamless and responsive user experience.

• Architected a scalable backend using Clean Architecture (Domain, Application, Infrastructure, Web).
• Implemented real-time synchronization using SignalR for instant order state updates.
• Designed domain-driven order aggregates with explicit lifecycle and pricing logic.
• Built advanced product customization with ingredient-level modifications and dynamic pricing.
• Developed admin dashboard for real-time kitchen operations and order management.
• Integrated PostgreSQL with Entity Framework Core for reliable data persistence.
• Containerized backend using Docker and implemented CI/CD pipelines.
• Exposed RESTful APIs with Swagger documentation consumed by React frontend.
