SwiftEats

Scalable food ordering platform with mobile app and robust backend API.

Problem Statement

Many food ordering platforms face backend systems that don't scale efficiently, complex cart logic that becomes difficult to maintain, and poor database design leading to performance issues. Tight coupling between frontend and backend systems often results in unreliable platforms.

Solution

SwiftEats was built as a modular, backend-driven system with a dedicated mobile application. The platform emphasizes API-first architecture using Go, RESTful services for core business logic, PostgreSQL for structured relational data, and role-based access control.

System Architecture

Go Backend

Modular REST API with authentication and authorization middleware

PostgreSQL

Relational schema optimized for transactional operations

Cart System

Flexible cart management with session consistency

Role-Based Access

Secured admin endpoints with middleware protection

API Design

Core Endpoints
GET/menu-items
POST/cart
GET/cart
POST/orders
*/admin/*

Challenges & Solutions

Designing a Flexible Cart System

Implemented stateless API architecture with efficient relational modeling to handle dynamic cart updates while maintaining data consistency across sessions.

Securing Admin Operations

Role-based authentication using middleware ensures only authorized users can access sensitive endpoints with clear separation between business logic and API layers.

Performance Under Concurrent Requests

Query optimization with indexed queries and Go's concurrency model maintain fast response times with multiple simultaneous users.

Key Takeaways

  • API-first architecture enables seamless integration across mobile and web clients
  • Modular design improves maintainability and extensibility
  • PostgreSQL with proper indexing handles transactional operations efficiently
