I need a web-based warehouse management system that pushes and displays data in real time—no page refreshes, no nightly batch jobs. When an item is received, picked, packed, or shipped, every open browser session must reflect the change instantly. The core focus is the real-time layer, so I’m happy to let you recommend the exact front-end and back-end stack (WebSockets, SSE, Firebase, or anything equivalent) as long as latency stays low and the solution remains browser-agnostic. A clean, responsive UI is a must because staff work from standard desktops and tablets on the floor. Key things I need from you: • A fully functional web application deployed to my staging server • Source code with clear comments and a concise README showing setup and tech choices • Basic seed data so I can run end-to-end tests immediately If you have experience integrating bar-code scanners, RFID, or existing ERP/APIs, mention it; I’ll likely extend the project after phase one.
