// CLIENT INDUSTRY D2C Retail & E-Commerce
// TECH STACK WordPress, Custom PHP, Vite, Tailwind CSS
// SERVICES PROVIDED Speed Remediation, Custom Theme Development
// PROJECT TIMELINE 4 Weeks Execution
// THE CHALLENGE

The Bottleneck: Legacy Infrastructure & Slow Load Times.

Conflicting Apps & Database Latency

The client was relying on 12 different third-party Shopify apps, causing severe script bloat, conflicting database calls, and a massive 4.5-second mobile load time. Operating in a high-volume B2B sector, every 100ms of checkout latency resulted in lost wholesale contracts and cart abandonment.

// THE ENGINEERING SOLUTION

The Architecture: Clean Code & Custom APIs.

Custom React Frontend

Bypassed heavy Liquid theme templates by building a headless React checkout extension that handles dynamic tiered wholesale pricing natively without page reloads.

Database & ERP Refactoring

Engineered a private GraphQL middleware in Node.js to bi-directionally sync 50,000+ SKU inventory levels between NetSuite ERP and Shopify in real-time (< 200ms).

Performance Remediation

Stripped 12 subscription apps, introduced critical inline CSS, WebP image pipelines, and edge caching for sub-1-second LCP rendering.
