Books by Fernando Magalhães
In-depth guides from 15+ years of enterprise software development. Concepts tested in production, written for engineers who build systems that matter.
SOLID Principles in Python
Stop memorizing SOLID and start applying it.
You've heard of the SOLID principles. Maybe you've even recited them in an interview. But spotting violations in a legacy codebase is different. Fixing them without over-engineering is even harder.
This book works with ShopFlow, a realistic order-processing system built from the ground up using Clean Architecture. You'll refactor it step by step, applying each SOLID principle to solve actual problems you'll face in production.
✓ Apply Single Responsibility to reduce coupling
✓ Use Open/Closed to extend without breaking changes
✓ Implement Liskov Substitution for reliable polymorphism
✓ Practice Interface Segregation for focused contracts
✓ Master Dependency Inversion for testable architectures
Software Engineering
Foundational principles for building systems that last.
Software engineering is more than writing code. This book covers the foundational decisions that determine whether a system thrives or becomes a liability. For engineers ready to think beyond tutorials and build for the long term.
You'll learn to make informed decisions about:
✓ Choose development processes that fit your team and project
✓ Elicit requirements that prevent scope creep and rework
✓ Evaluate architectures based on long-term maintainability
✓ Navigate trends like AI and cloud without chasing hype
✓ Implement testing and change management that reduce risk
