Ziwei Yang.

An all-in-one platform that helps restaurants and retail stores run their day-to-day operations — orders, sales insights, customers and digital menus — from a single dashboard. Built and launched from scratch as an independent product.

A platform for organising events and managing their communications, with generative AI woven throughout to draft content, review submissions and surface insights — cutting the manual, repetitive work teams usually face. Client project.

A subscription experience for a B2C online store: customers subscribe to products and receive them automatically on a recurring schedule, with recurring billing and order fulfilment handled end to end. Client project.

The website and booking platform for a group-travel agency, where travellers browse tours and destinations and book and pay for trips online, with the full reservation and notification flow automated. Client project.
