POS CHRONICLES — 2025 | Haru Li

DETAIL

The problem

A restaurant POS is operated constantly and forgives little: order state has to stay in sync across devices in real time, or the wrong dish goes out.

Approach

Built a tablet-optimized interface with React + Tailwind CSS, using WebSocket for real-time order and status updates. Integrated barcode scanning with support for multiple payment methods through checkout. Designed an extensible, maintainable frontend architecture around a high-frequency operation scenario.
