E-commerce Website

Overview

ExclusiveCPT is a production-ready e-commerce platform built from scratch to support the full purchase lifecycle—from browsing and cart management to secure checkout and order history. The TypeScript/React frontend is deployed on Vercel, while a Node.js/Express REST API runs on Railway.

The platform was designed for real customers with live payment processing, scalable cloud data storage, and security practices suited for both development and production environments.

Key Features

• Complete e-commerce flow with product catalog, cart, and checkout
• Dual authentication via email/password and Google OAuth 2.0
• JWT-based sessions with bcrypt password hashing
• Paystack integration for real-time GHS payment initialization and verification
• Supabase PostgreSQL for accounts, orders, and purchase history
• API hardening with CORS, Helmet.js, and token-based authorization middleware

Technologies Used

Project Highlights

A major milestone was migrating persistence from a file-based system to Supabase PostgreSQL, which improved reliability and enabled scalable storage of user accounts and purchase history as the store grew.

The project demonstrates end-to-end full-stack ownership—frontend UX, REST API design, payment gateway integration, database migration, and production security configuration across Vercel and Railway deployments.
