Event Management Platform Backend

A robust Django REST Framework-based backend system for managing large-scale events and workshops. This platform was successfully deployed on octenium.com via cPanel and handled 1000+ applications, serving both React Native mobile and React web applications.

📋 Project Overview

The Event Management Platform Backend is a comprehensive solution designed to streamline event management operations, including:

• Workshop scheduling and management
• Participant registration and attendance tracking
• Certificate generation and distribution
• Speaker and partner management
• Real-time notifications and confirmations
• Attendance tracking and reporting

🚀 Key Features

Event Management

• Workshop Management: Create, update, and manage multiple workshops with details like title, description, date, duration, and sessions
• Speaker Management: Manage speaker profiles with bio, images, and partner associations
• Partner Integration: Track and manage event partners
• Registration System: Handle workshop registrations with automatic email confirmations

Security Features

• Advanced Rate Limiting: Implemented throttling mechanisms to prevent abuse:
  • Registration throttling (minute, hour, and day-based limits)
  • Login and authentication throttling
  • Email confirmation throttling
• JWT Authentication: Secure token-based authentication using djangorestframework-simplejwt
• CORS Support: Configured CORS headers for cross-origin requests
• CSRF Protection: Cross-site request forgery protection enabled
• reCAPTCHA Integration: Google reCAPTCHA for form protection
• OTP Authentication: Two-factor authentication via django-otp

Attendance & Certification

• Attendance Tracking: Track participant attendance during events
• Certificate Generation: Auto-generate certificates for successful participants
• Cloudinary Integration: Cloud-based file storage for images and certificates

API Documentation

• Swagger/OpenAPI: Auto-generated API documentation using drf-spectacular
• RESTful Design: Standard REST API endpoints for all operations

🛡️ Security Measures (Post-Attack Implementation)

Due to security challenges encountered during the event, the following security measures were implemented:

• Rate Limiting: Multi-level throttling on registration, login, and email confirmation endpoints
• Input Validation: Comprehensive validation for all user inputs
• Email Verification: Confirmation-based email validation for registrations
• Token Management: JWT-based authentication with refresh token rotation
• Cloudinary Security: Secure file upload and storage with validation

📱 Client Support

This backend API serves:

• React Native Mobile Application: Native mobile app for attandens scanning
• React Web Application: Full-featured web interface for desktop users

   • Data type validation via serializers

3. Token Security: JWT with secure expiration

4. HTTPS Enforcement: Production deployments use HTTPS only

5. CORS Restrictions: Only whitelisted origins allowed

6. Database Security: Sensitive data encrypted where necessary
