Warehouse Management System
An enterprise-level dashboard built for a logistics client to track real-time inventory, speed up barcode lookups, and support offline-first scanner caching in connection dead zones.
The Challenge
The client’s fulfillment warehouse suffered from significant operational friction. Outdated paper inventory logs, network latency in updating inventory database states, and poor Wi-Fi connectivity in dark warehouse aisles led to frequent package barcode mismatches, average barcode scan lookup times exceeding 8 seconds, and system crashes during peak log sync cycles.
Our Approach
We designed a decoupled React-based single page application dashboard combined with an offline-first service worker architecture. Key solutions included an IndexedDB Scanner Cache to allow staff to scan products offline in dead-zones and auto-sync logs once connection was restored, custom React grid hooks to accelerate table rendering to under 150ms, and GTM telemetry integrations for error rate alerts.
Results & Impact
By eliminating dependencies on paper sheets and heavy synchronous database transactions, picking teams completed audits 60% faster. Scan log accuracy reached 99.9%, and the overall fulfillment error rate dropped to 0.1%, ensuring perfect inventory synchronizations.
