CarChoice - Digital Voucher System

A digital voucher platform for CarChoice, a Singapore car dealership, replacing paper vouchers with shareable digital ones. Customers receive a unique voucher link showing a branded voucher card with terms and conditions, live redemption status (including a "used" overlay once claimed), and a refer-a-friend offer with special voucher variants for expo and roadshow events. Staff manage everything from a back-office dashboard: voucher creation, expiration settings, redemption checking by code, customer records, analytics charts, and Excel exports. Built with Next.js 14, TypeScript, Zustand, and Tailwind CSS on the frontend, backed by a Dockerized Laravel REST API documented with OpenAPI.
