The Challenge

Managing Events at Scale

Event organizers often struggle with fragmented platforms for managing local and online events. Attendees need centralized discovery with filtered categories, while organizers require reliable RSVP capacity enforcement, attendance tracking, and secure session handling without over-engineered complexity. EventHub was built to bridge this gap by providing a unified, secure hub for all event operations.

Strategic Approach

Problem–Solution Mapping

Centralized Discovery

Resolved fragmented searching through category-based filtering and full-text search, allowing users to find tech, music, or food events instantly.

RSVP Capacity Control

Addressed overbooking risks with real-time atomic capacity enforcement and automatic availability checks during registration.

Hybrid Event Support

Bridge the gap between virtual and physical worlds with integrated support for online meeting links (Zoom/Meet) and physical locations.

Security Integrity

Implemented JWT auth stored in HTTP-only cookies with brute-force protection — automatic 2-hour lockout after 5 failed login attempts.

Under the Hood

System Architecture

Frontend

React 19 + Vite + Tailwind CSS with a responsive, dark-mode-first UI and Lucide iconography.

Backend

Node.js + Express 5 with MongoDB 9 (Mongoose 9) providing a scalable, schema-based REST API.

Database

MongoDB Atlas with Mongoose 9 ODM for flexible and scalable data storage.

Cloud Services

ImageKit for optimized media storage and Nodemailer (SMTP) for automated email notifications and password reset workflows.
