The Challenge

Event Discovery Was Friction-Filled

Most event tools were fragmented, hard to trust, and poorly designed for secure attendee workflows. I built EventHub to streamline discovery, booking, and management in a single platform with a consistent user journey.

Strategic Approach

Simplifying Event Discovery & Management

Smart Event Discovery

Built a discoverable event marketplace with rich filtering, category-based browsing, and stronger presentation so users can find relevant experiences faster.

RSVP Automation

Created a structured RSVP pipeline with capacity control, confirmation checks, and attendee tracking to reduce no-shows and booking confusion.

Secure Organizer Controls

Designed protected admin workflows with JWT cookies and rate limiting, ensuring event actions remain safe and predictable under load.

Operational Consistency

Unified event creation, attendance tracking, and status management into one app so users and organizers operate from the same source of truth.

Technical Decisions

Engineering Challenges & Tradeoffs

Authentication

HTTP-only JWT Cookies vs Local Storage

Chose secure cookie-based auth to reduce XSS exposure and keep session state protected across event workflows.

Reduced Client-Side Risk

Capacity Control

Server-Side RSVP Validation vs Client-Side Only

Enforced attendee limits server-side to prevent race conditions and guarantee integrity even when multiple users book simultaneously.

Reliable Capacity Enforcement

Under the Hood

System Architecture

Frontend

React 19 + Vite + Tailwind CSS — Clean event browsing, responsive cards, multi-step experiences, and a modular admin/dashboard UI.

Backend

Node.js + Express.js + MongoDB — REST APIs for event creation, attendee handling, authentication, and discovery workflows.

Security Layer

JWT authentication with HTTP-only cookies, rate-limiting, and request validation to prevent abuse and protect user sessions.

Operational Flow

Structured event lifecycle management from creation through RSVP tracking to final attendance and event status updates.

Impact & Results

Operational Impact

Reliable RSVP Flow

Standardized attendee management with fewer booking edge cases and better event readiness.

Safer Sessions

Cookie-based auth and rate limiting reduced exposure to common client-side and brute-force risk patterns.

Better Event Planning

Unified lifecycle management helped organizers coordinate discovery, attendance, and status updates more effectively.
