GemsHarbor is a B2B/B2C gemstone and jewelry marketplace. Tijani worked on the commerce workflows spanning product listings, user dashboards, auctions, bidding, offers, payment integrations, notifications, and order progression.
The problem
A specialist marketplace needs to support both product discovery and transaction workflows. Listings, auction activity, offers, payment status, notifications, and orders need to connect so buyers and sellers can follow a transaction through its stages.
Engineering constraints
- The marketplace supports product listings and user dashboards.
- Auctions and bidding add time-sensitive interaction to the commerce flow.
- Offers, payments, notifications, and order workflows must remain connected.
Tijani's role
Tijani worked on the marketplace and e-commerce workflows: listings, dashboards, auctions and bidding, offers, payment integrations, notifications, and connected order flows.
- Contributed product listing and marketplace experiences.
- Worked on user dashboards and auction/bidding workflows.
- Connected offer and payment steps to the order journey.
- Supported notifications across marketplace activity.
Marketplace transaction flow
The product combines B2B/B2C discovery with auction and e-commerce features. The documented scope spans the buyer/seller-facing surfaces and the connected transactions behind them, rather than a static catalog alone.
Project scope
The supplied resume identifies the major marketplace workflows but does not provide a technology stack, exact implementation ownership by feature, or quantified business outcomes. This write-up therefore focuses on the product and workflow areas that are explicitly documented.
