01 · Context
Vendors are the supply side of the platform: restaurants, kitchens, grocers. Their app is how they run their day: accepting orders, coordinating with riders, and getting paid. Every second of latency or missed push is real money lost.
02 · What I owned
- 01Built the order intake pipeline with tabs for incoming, ongoing, completed, and cancelled states.
- 02Owned the order-detail screen: customer notes, order summary, payment summary, and status transitions.
- 03Implemented the wallet & earnings module with balance, payouts, and transaction history.
- 04Set up push notification handling so vendors never miss an order, even from a cold start.
- 05Coordinated realtime sync with the customer and driver apps through a shared event bus.
03 · Interesting bits
· 01
Reliable push delivery via APNs with dedupe + local ringing for missed foreground notifications.
· 02
Instant list updates via WebSocket subscriptions, with graceful reconnect and backfill on resume.
· 03
Native-feeling swipe interactions on order cards using Reanimated 3.
· 04
Structured error boundaries so a single failing card never takes down the orders screen.
