.NET 8

E-Commerce Service Architecture

Enterprise-Grade E-Commerce Backend

Overview

A scalable e-commerce backend service built with .NET 8 that demonstrates enterprise-grade architecture patterns end to end. It applies Clean Architecture with complete separation of concerns across four distinct layers, keeping domain rules independent of frameworks and infrastructure. The result is a maintainable, testable foundation ready for horizontal scaling on Kubernetes.

What It Does

The service exposes RESTful endpoints for core e-commerce domain operations such as product and category management, with proper HTTP verbs, status codes, and resource modeling. Requests flow through an API layer into application services and repositories over EF Core and SQL Server, with global exception handling and layered validation guarding every operation. The application is containerized with multi-stage Docker builds and deployed to Kubernetes, with Docker Compose supporting local development.

Impact & Results

This project demonstrates expertise in building production-ready backend services using modern enterprise architecture patterns. The clean architecture approach with four distinct layers (API, Application, Domain, Infrastructure) ensures maintainability and scalability. The implementation showcases proficiency in SOLID principles, design patterns (Repository, Service, DTO), and modern DevOps practices including containerization with Docker and orchestration with Kubernetes. The comprehensive error handling, validation, and API documentation make this a reference implementation for enterprise e-commerce systems.
