StyleCart — Custom E-Commerce Platform
Migrated a fashion retailer off Shopify onto a custom Next.js storefront with Stripe payments, fast product search, real-time order tracking, and a full admin panel — cutting platform costs by $24k/year.
Project Overview
StyleCart is a fully custom e-commerce platform I built for a mid-sized fashion retailer who had outgrown Shopify. They needed a checkout flow tailored to their business rules, deep integration with their existing inventory management system, and the ability to run flash sales without hitting Shopify's API rate limits. I built the entire platform: a Next.js storefront with SSR for SEO, Elasticsearch for sub-100ms product search across 8,000+ SKUs, a custom cart and multi-step checkout with Stripe, real-time order tracking via webhooks, and a React-based admin panel for inventory, orders, and promotions. The result was a 98 Lighthouse performance score and a 22% lift in conversion rate.
Case Study
The Problem
The client was paying $2,000/month in Shopify Plus fees and hitting walls at every turn — they couldn't customise the checkout flow for their bundle pricing rules, couldn't integrate with their legacy inventory system without expensive middleware, and their product pages were loading in 4+ seconds because of Shopify's theme limitations. They were losing sales and paying too much for the privilege.
My Solution
I replaced their entire Shopify setup with a custom-built platform. The Next.js storefront uses SSR for every product and category page, giving Google exactly what it needs for SEO. Elasticsearch powers the search bar — it handles typos, synonyms, and filters across 8,000+ SKUs in under 100ms. The checkout is fully custom-built around their bundle pricing rules and connects directly to their inventory API. The admin panel gives their team full control over products, orders, promotions, and stock levels without touching code.
Results & Impact
- Eliminated $24,000/year in Shopify fees — platform paid for itself in under 12 months
- Page load time dropped from 4.2s to 0.9s — a 78% improvement in Core Web Vitals
- Conversion rate increased by 22% in the first 60 days after launch
- Admin panel cut order processing time from 8 minutes to under 90 seconds per order
