The landing page for buying partners
Problem
Deals ran through WhatsApp and WeChat threads, with no single place to track commitments against each deal's target.
Approach
Two role-based portals share one login. Admins post, edit and close deals and approve buyer sign-ups. Buyers browse deals, commit quantities, upload proof and request cancellations.
The commitment engine runs as an atomic database transaction, so concurrent commitments can never exceed a deal's target, and a deal closes automatically once it is filled.
Every deal moves through a clear lifecycle: open, filled, expired or closed.
My role
I lead development of the platform as a freelance engagement with 888Group, from architecture and the commitment engine to testing and production.
Engineering
A layered architecture (models, repositories, services and controllers) with zod-validated inputs, realtime deal notifications, an audit log and CI with Playwright end-to-end tests.
