What is hexagonal architecture (or “Ports & Adapters”, as this architecture is officially called)? What are its advantages over other architecture patterns? How to implement software with hexagonal architecture?
Software Craftsmanship
Many of us have learned programming autodidactically. But little have we learned about how to write code that is easy to read and change, even for other developers, and how to design complex software that is “soft” (i.e., changeable and maintainable with as little effort as possible) and remains so throughout its lifetime of possibly years to decades.
This is where Software Craftsmanship comes in. The goal of Software Craftsmanship is to increase the quality of software through education and ongoing training of developers. The range of topics includes:
- Clean architecture
- Clean code
- Coding dojos and katas
- Design patterns
- Design principles (SOLID)
- Domain-driven design
- Recognizing and eliminating code smells
- Object-oriented programming
- Object-oriented design
- Pair programming
- Refactoring
- Static code analysis and code quality metrics
- Technical debts
- Test-driven development

My blog features many articles on Java, software architecture, and performance — from foundational concepts to advanced patterns.
If you want to go deeper, check out my trainings: hands-on, easy to understand, and directly applicable to your day-to-day project work. Instead of theory, I teach principles that help you write code that is better, more maintainable, and more performant in the long run.
