Clean Architecture: Introduction
Start with the fundamentals. Clean Architecture rests on sound architectural principles — you will learn how to apply them to design applications that stand the test of time.
Domain Layer and Domain-Driven Design
Build a rich domain model with Domain-Driven Design. We cover domain modeling best practices and introduce the application we will build throughout the course.
Application Layer and CQRS
How do you implement CQRS and solve cross-cutting concerns with ease? Here you will learn how to design your application use cases cleanly.
Infrastructure Layer
Implement a blazing-fast persistence layer using the most advanced EF Core features. We also tackle concurrency problems and their solutions.
Presentation Layer
How do you add API endpoints efficiently and set up dependency injection the right way? You will find all the answers (and more) here.
Authentication and API Security
Robust JWT authentication is a must to secure your API. You will learn how to integrate an external identity provider with Keycloak.
Authorization, Roles and Permissions
Authentication is nothing without fine-grained access control. Implement role-based authorization paired with custom permission-based policies.
Outbox, Structured Logging, Redis
Reliably publish messages with the Outbox pattern, and implement cross-cutting concerns like structured logging, health checks, and distributed caching with Redis.
Testing Clean Architecture
Get maximum confidence in your system. We cover unit, integration, and functional testing, plus enforcing your architecture with architecture tests.
More than just theory
Pragmatic Clean Architecture includes more than video lessons. I built it with bonus resources so you actually apply what you learn.

Who's behind this
Hi — I'm Milan Jovanović. I help engineers level up their .NET and software architecture skills.
I'm a Software Architect and Microsoft MVP for Developer Technologies with years of experience building large-scale systems.
I've helped thousands of engineers improve through my practical tips on social media, The .NET Weekly newsletter, and YouTube channel.
My goal is to teach you everything I learned building and maintaining production-ready applications with Clean Architecture.
Got questions?
Frequently asked questions
Who is this course for?
This course is for anyone who wants to learn how to apply Clean Architecture in the real world — and use it to create testable, maintainable, large-scale systems.
It's also for anyone who wants to learn the principles of Domain-Driven Design. The course focuses on tactical DDD patterns and how to apply them in practice.
What will I learn in this course?
The best practices for building production-ready applications using Clean Architecture — the same core principles I've used to build many large-scale systems.
- Clean Architecture fundamentals
- Domain-Driven Design
- CQRS
- Authentication & authorization
- Testing
All course content is updated to .NET 8.
How long is the course?
The course is 6 hours and 21 minutes of video, packed with value and designed to be easy to follow.
What does Community Access mean?
With the PCA + Community Access plan you gain access to the Community section — a great way to enhance your learning if you don't want to go through the course alone. It's where like-minded engineers collaborate and get help, and I'll be there to answer questions too.
What is the Advanced CA template?
A bonus for students who enroll in the PCA + Community Access course. It's a Clean Architecture template that helps you quickly start new projects.
What makes it advanced? It comes with more features built in — like messaging over a message broker, telemetry, Minimal APIs setup, and more.
Got it. This must be expensive, right?
No. It's $247 on the basic plan.
And if you want Community access with like-minded engineers, it's $397.
Can my company pay for the course?
Absolutely — many students expense the course through their employer. You'll receive a receipt after checkout that you can submit for reimbursement. If you need anything else, like a quote for multiple team seats, contact me.
Do I get lifetime access?
Absolutely, yes! You can access the course forever, including any future updates, with no extra payment.
What are the prerequisites for taking this course?
You should have at least 1 year of experience with ASP.NET Core and (preferably) Entity Framework Core. Beginners will still improve, but it'll be slightly harder to follow. You should also be familiar with Docker, which we use for running external services.
What if I get stuck during the course?
The course is carefully designed to build knowledge progressively, so the chances of getting stuck are minimal.
If you do need help, the Community Access edition gives you direct access to me and other participants.
