If I were starting today

If I had to start over today and learn software architecture, this is the path I would follow.

Step 1 — Set the right mental model

Watch this short video. This is about understanding why business logic must NOT depend on data stores or external APIs.

Step 2 — Start with a solid architectural pattern

To become a Software Architect, you need a solid architectural pattern to structure your code. Hexagonal Architecture is the right place to start.

Download the Hexagonal Architecture PDF and browse the GitHub project.

This gives you the code structure discipline.

Step 3 — Watch a real system built from scratch

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 teaches how to build the inside correctly.

Step 4 — See a real system end-to-end

Now you zoom out.

Good architects design their diagrams based on the target audience. Business people never enjoy your technical diagrams. Developers admires who explain the why behind decisions.

You’ll walk through:

uses cases analysis, and seeing the big picture
infrastructure and architecture
design by volatility (reasons of change)
component decomposition

This teaches how real systems are designed and explained.

Step 5 — Make it survive growth

Scalability is the thing that separates good web applications from excellent ones.

You’ll learn:

caching, queueing, data storage locks, and redundancy
why systems break under load

This teaches how designs hold under stress.

Clean Architecture Pattern Hands-On

Course
21 Lessons

This course aims to create loosely coupled components that can be tested independently with no dependencies on data stores, message brokers or UIs. This pattern helps prevent technology lock-in. It covers folder setup, core domain logic (anemic vs. rich), use case orchestration, and plugin gateways implementing core interfaces.

Digital Bank Architecture

Course
15 Lessons

Good architects design their diagrams based on the target audience. Business people never enjoy your technical diagrams. Developers admires who explain the why behind decisions. This course navigates a real digital banking solution. Starting with the use cases analysis diagram all the way to components diagrams, explaining the why behind each design and architecture decision.

To become a Software Architect, you need a solid architectural pattern to structure your code. Hexagonal Architecture is the right place to start. This document explores how the Hexagonal Architecture pattern helps teams build systems that can absorb changes gracefully, supported by a practical example: executing a money transfer in an online banking system.

Web Applications Scalability

Course
11 Lessons

This course includes lessons on the 5 components of highly scalable web applications. From caching and queueing to minimizing storage locks, handling asynchrony, and building redundancy, Scalability is the thing that separates good web applications from excellent ones. If you’re serious about building apps that don’t crumble under load, this is for you.
