Project Overview

A comprehensive e-commerce platform built from the ground up to handle high-traffic retail operations. The platform features real-time inventory management, secure payment processing, and an intuitive admin dashboard for store management.

Problem Statement

The client needed a modern, scalable e-commerce solution to replace their outdated system. The existing platform suffered from slow load times, poor mobile experience, limited payment options, and couldn't handle traffic spikes during sales events. They were losing an estimated 30% of potential customers due to cart abandonment caused by technical issues.

Solution Approach

1

Implemented a headless architecture using Next.js for the frontend, enabling blazing-fast page loads with server-side rendering and static generation for product pages.

2

Built a robust Node.js backend with NestJS framework, implementing clean architecture principles for maintainability and scalability.

3

Integrated Stripe for secure payment processing with support for multiple payment methods including cards, wallets, and buy-now-pay-later options.

4

Designed a real-time inventory system using PostgreSQL with Redis caching to handle concurrent orders without overselling.

5

Created a comprehensive admin dashboard with analytics, order management, and inventory controls.
