The context
A business marketplace needs a clear path from a seller joining the platform to a listing being managed and made available to buyers.
SG Business Mart brings seller workflows, business listings, paid plans, administration, and payments into that product experience.
The workflow
The platform connects seller onboarding with the listing lifecycle and paid plans. Administration supports the operations around those listings.
- Sellers enter the product through onboarding and listing workflows.
- Paid plans and payment handling support the commercial side of a listing.
- Administration provides the tools to manage the marketplace as it develops.
My contribution
I built the platform from the ground up, including architecture, database design, listings, seller workflows, admin operations, and payment integrations as the product evolved.
The payment work includes Stripe Checkout, webhooks, and payment status handling, alongside HitPay integration.
What connects the work
Listings, sellers, plans, and payment states belong to the same product lifecycle. Working across the stack helped me carry that context from data design to the user-facing workflow.
The delivered scope
The work covers the marketplace foundation and the seller, administration, and payment workflows supporting it as the product evolved.
