Overview
Deal-Delivery is a multi-tenant delivery orchestration SaaS. It lets any business (online stores, restaurants, pharmacies, ERPs) request and manage deliveries without building its own logistics system: pricing, driver dispatch, delivery lifecycle, real-time tracking, cash collection, financial settlement, and integration APIs. It is production-ready.
It has four portals: Merchant, Admin, public Tracking, and a React Native driver app.
Highlights
- tRPC 11 modular monolith (21 domains, 145 procedures) with dual tenant-isolation axes (merchant marketplace vs. internal fleets), enforced by procedure-level middleware and database constraints.
- PostGIS geospatial dispatch engine backed by 6 BullMQ worker queues.
- Real-time delivery tracking over SSE with sequence-based replay on Redis pub/sub, plus immutable financial snapshots and self-balancing driver wallets.
- React Native driver app with background GPS tracking, a local SQLite buffer queue, and batch sync with server-side soft throttling.
