AT A GLANCE

My role: Sole designer and developer
Technology: JavaScript (no framework) · PWA + service worker · localStorage · USD / L.L. · Arabic RTL

The problem

Lebanese shops price in dollars but are paid in dollars and lira at once, and the connection drops. The register has to give the right change in two currencies and keep selling offline.

What I built

Dual-currency maths: prices in USD, lira totals from an editable exchange rate (with history) rounded to the cash denomination, split payments across both currencies and generated change options.
Offline-first PWA: a service worker caches the app shell (pages network-first, assets stale-while-revalidate). I tested reloading with the network off.
Kitchen display and customer screen stay in sync with the register through shared storage events: no server needed.
Owner / manager / cashier permissions, an audit trail with cashier risk scoring and cash-variance checks, QR menu, WhatsApp receipts, Arabic RTL.

A register that keeps selling when the connection does not.

The design brief centres on presenting POS 2026 clearly to its audience, with an understandable content hierarchy and an easy next step.

Clear spacing, purposeful imagery and navigation that fits the screen. The screenshots and project link let you judge the details directly.
