DotShop E-commerce Backend Development

Overview

DotShop is a modern e-commerce backend built with ASP.NET Core 8. It handles authentication, product lifecycle, order management, and secure role-based flows with clean, modular architecture. The system follows enterprise-grade patterns: DTOs, AutoMapper, EF Core migrations, repository/service separation, proper JWT authentication flows, and stock-safe order handling.

Problem / Context

Most small-to-mid e-commerce teams need a backend that is:
Secure
Easy to extend
Strongly typed
Compatible with SQL Server
Production-ready but lightweight
DotShop solves these needs with a clean .NET architecture that is easy to onboard developers into while supporting real business logic like inventory, orders, and role-based administration.

Architecture Overview

Key layers:

Controllers: Handle routing and HTTP translation
Services: Business logic (stock check, order totals, validation)
Repositories: Encapsulated DB operations
DTOs + AutoMapper: Clean input/output boundaries

Product Management

CRUD with validation
Stock checks
Soft constraints to prevent invalid updates
AutoMapper for clean DTO → model mapping

Order Management

Place/update/delete orders
Per-user order history
Automatic total-price calculation
Stock deduction validation (prevents oversell)

Developer Experience

Full Swagger/OpenAPI UI
Clean project structure
EF Core migrations with separate contexts (App + Auth)
Consistent error handling middleware

Technical Decisions & Why They Matter

ASP.NET Core 8

Fast, reliable, and modern — ideal for scalable APIs.

Entity Framework Core

Speeds up development
Supports clean migrations
Allows easy DB switching (SQL Server → PostgreSQL if needed)

Separate AuthDbContext

Keeps user/auth tables isolated → fewer production mistakes, easier scaling.

DTO + AutoMapper

Prevents over-posting, keeps controllers clean, and ensures consistent mapping logic.

Repository + Service Pattern

Code stays testable and structured. Future developers can modify logic without breaking controllers.

Results & Impact

These outcomes are what clients care about:
Predictable order processing
Safe stock management
Clean JWT-based security
Fast endpoint responses via optimized queries
Easy onboarding for new team members
Scalable architecture suitable for real stores

Why this project matters

This project demonstrates:
Mastery of .NET backend fundamentals
Clean production structure (services, DTOs, repositories)
Secure authentication implementation
Real-world e-commerce domain knowledge
Ability to ship a complete backend independently
