Overview

Hoàn Hời is a cashback platform for Vietnamese shoppers. Before buying, users open a product through a Hoàn Hời link; the marketplace pays a commission for that order, and Hoàn Hời shares most of it back to the user's wallet.

I built the product end-to-end and run it in production at hoanhoi.com.
