Portfolio Case Study: Inventory Synchronization for Apparel Retail

---

The Challenge

This clothing brand faced a critical operational bottleneck: their Shopify storefront and physical warehouse management system were consistently out of sync. This led to frequent overselling of out-of-stock items, resulting in customer service headaches, forced refunds, and manual inventory reconciliations that took hours every week. The brand was scaling quickly, and their manual "check-and-update" process was failing to keep pace with order volume.

The Process

To solve the synchronization gap, I developed a custom middleware application using Node.js and the Shopify GraphQL Admin API. My approach focused on building a resilient polling system that could handle the brand's high SKU count without hitting API rate limits.

I implemented a webhook-based architecture to capture real-time order data and a scheduled worker to pull inventory levels from the warehouse API every five minutes. A key technical decision was building a custom error-handling and retry logic layer, ensuring that even if one API experienced downtime, the data integrity remained intact. This moved the brand from a reactive manual workflow to a fully automated, high-frequency synchronization engine.

The Proof

The automation immediately eliminated the need for manual inventory audits. Since deployment, the brand has reported a 99% reduction in overselling incidents. By automating the sync, the operations team reclaimed approximately 12 hours per week previously spent on manual data entry and refund processing. The system now handles over 500 daily inventory updates with zero manual intervention.

"The inventory issues were our biggest growth blocker. This app fixed the problem overnight and let us focus on sales again."
