Building a complete logistics engine isn't just about rendering CRUD forms. Real-world delivery applications require complex state machines, real-time dispatching logic, dynamic fare calculations, and multi-actor security roles.
I recently finished architecting and releasing a production-ready **courier & logistics management system. Here is a technical breakdown of how I structured the architecture, solved the dispatching problem, and decoupled the backend for scale.
🏛️ System Architecture Overview
To ensure high performance and future extensibility (such as plugging in native iOS or Android apps down the road), I separated the core backend completely from the web presentation layer.
- Backend: ASP.NET Core (.NET 10) Web API
- Frontend: ASP.NET Core MVC consuming the API
- Styling: Tailwind CSS + SweetAlert UI event feedback
- Database: PostgreSQL (Relational schema with custom indexing) ## ⚙️ Key Technical Challenges & Solutions
1. Dynamic Distance-Based Pricing
Flat fees don't work for logistics startups. Long-distance trips undercharge the driver, while short trips turn away customers.
I implemented a dynamic pricing algorithm inside the API engine that computes the delivery total using standard route parameters:
$$\text{Total Fare} = \text{Base Fee} + (\text{Distance in km} \times \text{Per-km Rate})$$
This allows administrators to adjust regional base fees and per-kilometer rates globally without modifying codebase rules.
2. Automatic Rider Dispatch Engine
Manual dispatching creates massive operational bottlenecks. The system includes an automated assignment dispatcher that runs upon order creation:
- Queries the PostgreSQL database for active riders marked as
Available. - Evaluates current workload queues.
- Automatically attaches the order to the selected rider's active manifest.
- Triggers instant updates in the dedicated Rider Portal.
3. Multi-Portal Isolation & Security
The system features 4 dedicated portals:
- Admin Portal: Fleet management, rate configurations, global reporting, and user roles.
- Client Portal: Order creation, real-time shipment tracking, and delivery history.
- Rider Portal: Mobile-first dashboard for active pickups, status updates, and daily run metrics.
-
Order Management Portal: State machine handling transitions (
Pending➔Dispatched➔In Transit➔Delivered/Cancelled).
Security includes token-based authentication and a complete email recovery flow for lost passwords.
