EventFlow

Inspiration

College events are often managed through Google Forms, spreadsheets, and manual attendance sheets. This process is time-consuming, error-prone, and lacks real-time visibility for both students and organizers. We wanted to create a smart platform that simplifies event registration, improves attendance tracking, and leverages AI to reduce administrative effort.

The biggest inspiration was solving two major problems:

Managing event registrations efficiently.
Preventing attendance fraud through a secure verification system.

What it does

EventFlow is an AI-powered College Event Registration and Smart Attendance Portal.

The platform allows:

Students to browse and register for events.
Administrators to create and manage events.
Real-time tracking of registrations and available seats.
Secure attendance verification using Admin Generated Dynamic QR Codes.
Attendance analytics and reporting.
Excel and PDF attendance exports.

Additionally, EventFlow integrates Gemini AI to automatically generate professional event descriptions, agendas, requirements, and benefits, helping organizers create events faster.

How we built it

Frontend:

React.js
Vite
Tailwind CSS
Context API

Backend:

Node.js
Express.js

Database:

MongoDB Atlas
Mongoose

Authentication:

Role-Based Authentication (Admin & Student)

AI Integration:

Google Gemini API

Attendance System:

Dynamic Admin QR Generation
QR Scanning
Backend Verification
Automated Attendance Marking

Reporting:

Excel Export
PDF Export

The application follows a modern dashboard-based architecture with separate admin and student portals.

Challenges we ran into

Migrating the project from Firebase Firestore to MongoDB Atlas.
Designing a secure attendance mechanism that prevents proxy attendance.
Implementing QR-based attendance verification while keeping the user experience simple.
Managing role-based access control between Admin and Student users.
Making the platform fully responsive across desktop, tablet, and mobile devices.
Handling database connectivity and deployment-related issues.
Integrating Gemini AI seamlessly into the event creation workflow.
