alt Hacker NewsJust built a last-mile logistics management solution to replace a SaaS solution for a delivery company I used to be involved with.
Handles everything from real-time driver tracking, public order tracking links, finding suitable drivers for orders, batch push notifications for automatic order assignment, etc.
Backend: Feathers.JS, Postgres + TimescaleDB & PostGIS, BullMQ, Valhalla (for multi-stop route optimization although most of our deliveries are on-demand)
Frontend: SvelteKit
Mobile App (Android only for now): React Native/Expo, Zustand, Expo push notifications, and two custom native modules for secure token storage and efficient real-time GPS tracking. The tracking was probably the toughest to get right to find the best balance between battery/data efficiency and more frequent updates.
Been testing it for a couple weeks and as of last week, that company moved their operations over to it with 50+ drivers and thousands of orders processed through it so far (in a country with pretty unreliable connectivity/infrastructure).
I built it initially as a favor but open to other applications for it.

That's a hell of a favor. Is this something you built by yourself or were you part of a larger team?
Sounds very interesting. I'd love to take a look if open source?
Would you be interested in sharing the code? I'm working a similar project and wouldn't mind exploring your code base.
