Backend Portfolio Project

Ride BookingBackend System by Aniket Kumawat

A scalable backend system for a ride booking platform built using Java and Spring Boot that enables users to request rides and drivers to manage ride assignments.

About the Project

Understanding the System

A comprehensive backend solution designed to handle the complexities of ride booking platforms.

This project was built to simulate the backend of popular ride-sharing applications like Uber or Ola. The primary focus was on creating robust REST APIs, implementing secure authentication mechanisms, and designing an efficient database schema.

The system follows Spring Boot best practices with a clean, maintainable architecture that separates concerns across different layers. This approach ensures scalability and makes the codebase easy to understand and extend.

Controller Layer

Handles HTTP requests and responses. Defines REST endpoints and validates input data before passing to the service layer.

  • REST endpoint definition
  • Request validation
  • Response formatting
  • Error handling
Service Layer

Contains business logic and orchestrates data flow. Processes requests, applies business rules, and coordinates transactions.

  • Business logic
  • Transaction management
  • Data transformation
  • Service orchestration
Repository Layer

Manages data persistence and retrieval. Uses Spring Data JPA for database operations with custom query support.

  • CRUD operations
  • Custom queries
  • Data mapping
  • Connection management
Database Layer

MySQL database for persistent storage. Stores user data, ride information, reviews, and system notifications.

Features

Powerful Backend Features

A comprehensive set of features designed for modern ride booking platforms.

User Management

Register and manage user accounts with secure authentication. Users can create profiles, update information, and manage their ride history.

Driver Management

Drivers can register, accept rides, and manage their availability. Complete driver onboarding with vehicle information and verification.

Ride Booking

Users can request rides with pickup and drop-off locations. Real-time ride tracking and status updates throughout the journey.

Reviews & Ratings

Users can review drivers and provide ratings after each ride. Build trust and maintain quality service through feedback system.

Secure APIs

Spring Security implementation for authentication and authorization. JWT-based token authentication for secure API access.

Notifications

System notifications for ride updates, driver assignments, and important alerts. Keep users informed about their ride status.

Database Design

Entity Relationship Model

Well-structured database entities with clear relationships and optimized queries.

User

Stores user information including name, email, phone number, and authentication credentials. Tracks user ride history and preferences.

Driver

Contains driver profiles with vehicle details, license information, availability status, and performance metrics.

idnamelicensevehicleratingstatus
Ride

Records ride requests with pickup/drop-off locations, fare calculations, ride status, and timestamps.

API Endpoints

RESTful API Design

Well-documented REST endpoints following best practices. All APIs tested using Postman.

Sample Endpoints
Core API endpoints for the ride booking system
GET/api/rides
POST/api/rides/request
POST/api/users/register
POST/api/drivers/register
POST/api/reviews
GET/api/drivers/available
PUT/api/rides/{id}/status
GET/api/users/{id}/history
Example Response
Sample JSON response from ride endpoint
{
  "id": 1,
  "pickup": "123 Main Street",
  "dropoff": "456 Oak Avenue",
  "fare": 15.50,
  "status": "IN_PROGRESS",
  "user": {
    "id": 1,
    "name": "John Doe"
  },
  "driver": {
    "id": 1,
    "name": "Jane Smith",
    "vehicle": "Toyota Camry"
  },
