TradeWave needed to make reverse auctions intuitive for buyers and manageable for sellers on both iOS and Android.
The problem
Bid timing, listing state, notifications, and seller actions could easily produce inconsistent experiences across two mobile platforms.
The approach
We defined one auction state model and one shared component system before building the buyer and seller journeys.
Technical implementation
- +Shared cross-platform mobile component library.
- +Server-owned auction state with real-time client updates.
- +Push notifications for bids, expiry, and seller actions.
- +Operational tools for listings, disputes, and moderation.
Outcome
The marketplace shipped on iOS and Android with predictable patterns for users and the product team.
