Overview

CampusBay is a campus-exclusive peer-to-peer marketplace I'm building for University of Malaya students — entirely solo, as a self-development project. A trusted, verified space to buy and sell textbooks, electronics, hostel furniture, and more within the UM community.

Registration is gated to @siswa.um.edu.my and @um.edu.my email addresses, verified via OTP — every user is a real UM student, eliminating scammers common on Carousell or Facebook Marketplace.

The stack is production-grade: React 18 + Vite frontend, Node.js + Express backend, PostgreSQL + Redis for data and caching, Socket.io for real-time features, and Stripe for payments — containerised with Docker Compose and self-hosted on a Linux mini PC.

Key Features

UM Email Verification + OTP

Registration gated to @siswa.um.edu.my accounts. 6-digit OTP via email, stored in Redis with TTL. Unverified accounts can't transact.

Real-Time Chat

Socket.io-powered buyer–seller messaging with typing indicators, read receipts, and push notifications when the recipient is offline.

Stripe Payment + COD Scheduling

Full Stripe Checkout integration (MYR) with webhook-driven order fulfillment and atomic stock decrement. COD via in-app meetup scheduler.

Flash Sales & Vouchers

Sellers can create time-bounded flash sales with discounted pricing. Buyer-redeemable vouchers with usage limits and expiry.

Wishlist, Reviews & Seller Follows

Buyers can wishlist items and follow sellers. Product ratings and reviews. Notification bell for live updates across all activity.

Admin Dashboard

Platform-wide analytics, user management, product moderation. Role-based access: buyer, seller, admin.

A self-development project, built from scratch.

Every line of code — from the Docker Compose stack to the Stripe webhook — written solo. CampusBay is where I apply and stretch everything I learn, shipping real features to a real domain.
