Case Study — E-Commerce

E-Commerce Platform

A high-performance e-commerce platform featuring lightning-fast product filtering, secure checkout integrated with Stripe, automated inventory tracking, and a responsive customer dashboard.

Project Overview

This high-performance storefront was designed to maximize checkout conversions. Leveraging Next.js Server Components, the store ranks exceptionally high on technical SEO and loads in under 1 second. Payments are handled securely using Stripe Elements, supporting Apple Pay, Google Pay, and standard credit cards. The admin dashboard provides instant updates on daily sales, inventory volumes, and product page analytics.

Key Features & Scope

Next.js Server Side Rendering (SSR) for instantaneous page loading

Stripe webhook integrations securely fulfilling transactions in background

Intelligent product filter panels updating queries instantly without page refreshes

Real-time database triggers updating store inventory counts after every checkout

System Architecture

Built using Next.js App Router for server components and optimal performance. Data layer uses Supabase's PostgreSQL with optimized views. Stripe webhook routes verify signatures and update user transaction states securely.

Biggest Challenge & Resolution

The Challenge

Product filtering with hundreds of SKUs caused slow database queries, and Stripe webhook race conditions occasionally led to duplicate order fulfillment or missed inventory decrements.

The Resolution

Optimized PostgreSQL queries with composite indexes and materialized views for filter combinations. Implemented idempotent Stripe webhook handlers with signature verification and database-level advisory locks to prevent duplicate processing, achieving sub-100ms checkout completion.
