Foundations gives you code discipline.
You will learn how to structure business logic so it stays independent from databases, message brokers, and UI code.
You will see architectural patterns like Hexagonal and Clean Architecture implemented in real code. You will understand how to enforce clear team boundaries and write clean code like an architect.
Save time and money.
If I had to start over today, this is the path I would follow.
Watch this short video. This is about understanding why business logic must NOT depend on data stores or external APIs.
You need a solid architectural pattern to structure your code properly. Hexagonal Architecture is the right place to start.
This gives you the code structure discipline.
Watch me building the solution from scratch. Covering: folder setup, core domain logic (anemic vs. rich), use case orchestration, and plugin gateways implementing core interfaces.
You’ll learn:
how to organize use cases and domain logic
how to keep the core independent
how to plug databases, UIs, and message brokers without polluting the core
This shows you how to build the inside correctly.
Watch me refactoring code that smells bad!
Earn the respect of your software developers by mastering the art of combining different refactoring techniques.
This hands-on course will transform you into a clean coder!
