Shopway is a .NET 8 e-commerce backend application built on a clean architecture with a CQRS-based application layer. It manages products, orders, and user accounts, supporting features like fuzzy search, batch processing, and two-factor authentication. The system utilizes a SQL database with an outbox pattern for reliable event handling and provides both minimal and FastEndpoints API surfaces for client interaction.

How it got here

2022–2023 · Clean Architecture and CQRS Implementation

The codebase was restructured into a strict Clean Architecture with distinct layers for Domain, Application, Infrastructure, and Presentation, each supported by comprehensive documentation and unit tests. The implementation introduced CQRS with MediatR, Ulid-based identifiers, and robust pagination and batch processing capabilities. This period focused on establishing the foundational domain models, persistence patterns, and API endpoints required for the Shopway application.

2024 · Dynamic query and payment gateway integration

This period focused on implementing a generic proxy framework to enable dynamic filtering, sorting, and mapping for entities like OrderHeader and Product. It also introduced a new user and role-based authorization model and integrated a dummy payment gateway service.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 53167e9025 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
