Safino - Fast Delivery of Hot Traditional Persian Bread

I developed Safino, a Progressive Web App (PWA) that enables fast delivery of hot traditional Persian bread to customers' doorsteps. The platform is designed to provide a seamless experience for customers, delivery personnel, and administrators. Customers can place orders, track their delivery in real-time, and receive their bread hot and fresh. Delivery personnel use the app to manage orders and optimize routes, while administrators oversee operations through a comprehensive admin panel.

2. Fast Order Placement:

   • Customers can quickly select and order traditional Persian bread.
   • Real-time inventory updates ensure accurate order fulfillment.

3. Real-Time Order Tracking:

   • Customers can track their orders in real-time on an interactive map.
   • Delivery personnel receive optimized routes for efficient deliveries.

4. Delivery Personnel App:

   • Delivery personnel can manage orders, view routes, and mark deliveries as complete.
   • Integrated with GPS for real-time location tracking.

5. Admin Panel:

   • Administrators can manage orders, track delivery personnel, and monitor inventory.
   • Provides analytics and reports for business insights.

6. Scalable Backend:

   • Built with FastAPI for robust and scalable APIs.
   • Uses PostgreSQL for structured data storage.

7. Modern Frontend:

   • Developed with React, Next.js, and TailwindCSS for a responsive and user-friendly interface.
   • State management handled by Zustand.

8. Cloud Integration:

   • Stores images and static assets in AWS S3 for scalable and cost-effective storage.

9. CI/CD Pipeline:

   • Implemented GitHub Actions for automated testing and deployment.
   • Ensures smooth and efficient development workflows.

10. Self-Managed Infrastructure:

    • Managed servers and deployment environments independently.
    • Utilized Docker for containerization and deployment.

Backend:

• FastAPI: For building robust and scalable APIs.
• PostgreSQL: Primary database for storing order and user data.
• Docker: Containerization for seamless deployment.
• AWS S3: Cloud storage for images and static assets.

Frontend:

• React: For building interactive user interfaces.
• Next.js: Server-side rendering and routing.
• TailwindCSS: Utility-first CSS framework for styling.
• Zustand: State management for complex frontend logic.

DevOps:

• GitHub Actions: CI/CD pipeline for automated testing and deployment.
• Docker: Containerization for consistent environments.
• Self-Managed Servers: Handled server setup, scaling, and maintenance.

1. Real-Time Order Tracking:

   • Challenge: Implementing real-time order tracking with minimal latency.
   • Solution: Used WebSocket for real-time communication and integrated with GPS for accurate location tracking.

2. Offline Functionality:

   • Challenge: Ensuring the PWA works offline and syncs data when online.
   • Solution: Implemented service workers and local storage for offline functionality and data synchronization.

3. Scalability:

   • Challenge: Building a system that can scale with increasing users and orders.
   • Solution: Adopted a microservices architecture with FastAPI and used AWS S3 for scalable storage.

4. Delivery Route Optimization:

   • Challenge: Optimizing delivery routes for efficiency.
   • Solution: Integrated with third-party routing APIs to provide optimized routes for delivery personnel.

Safino has transformed the way traditional Persian bread is delivered, providing a fast, reliable, and user-friendly platform for customers, delivery personnel, and administrators. The PWA ensures a seamless experience, while the scalable backend and modern frontend technologies ensure high performance and reliability.
