PickLight

Smart warehouse picking system built with Laravel, Livewire, and Filament.

Overview

PickLight is a warehouse-assisted picking solution that guides packers through delivery note processing using RFID authentication, illuminated shelf slots, OLED displays, weight validation, DHL shipping labels, and Xentral ERP integration.

The system is designed for multi-station warehouse environments where employees process delivery notes quickly and accurately with minimal manual input.
