Architecture
Robust 3-Tier Design
The system is built on a strict 3-tier architecture to ensure maintainability and scalability. The Presentation layer communicates via HTTP with the Business layer, which handles Data Persistence through Entity Framework Core and SQL Server.
- ✓Presentation Layer: React, Redux Toolkit, and Material-UI for a highly responsive user experience.
- ✓Business Layer: ASP.NET Core Web API handling complex routing, business logic, and JWT-based authentication via Microsoft Identity.
- ✓Persistence Layer: SQL Server integration utilizing both Entity Framework Core for complex relational queries and Dapper for high-performance read operations.
Database Design
Complex Relational Modeling
The database was meticulously modeled to handle the realities of a multi-vendor, multi-role e-commerce environment. It features advanced table inheritance strategies for user roles and deeply normalized product characteristic mappings.
Data Integrity & Inheritance
A core 'User' entity is extended into specific roles (Administrator, Client, Deliverer) to enforce strict access control. Products are heavily normalized to support dynamic categories, sub-categories, specific characteristics, and hierarchical discounting.
Features
Comprehensive User Journeys
- •Client Experience — Advanced multi-criteria search (by category, brand, price range, availability), persistent cart management, multi-step checkout with local payment options (Airtel Money, Orange Money), and order tracking.
- •Administrator Dashboard — Secure interface to manage product catalogs with multiple image uploads, dynamically assign deliveries to specific couriers based on neighborhoods, and track overall platform health.
- •Deliverer Portal — Dedicated views for couriers to list assigned orders and update delivery statuses in real-time.
