Workshop: How the right architecture helps you make big changes

You want to move to a different framework, or maybe you have to upgrade that really outdated library, but where do you start? And how do you do that in small steps? This talk shows you how architectures and techniques like hexagonal, vertical slice and domain driven design can help you move through big transformations, while at the same time increasing your code quality!

Like many of us, your codebase is likely not a nice small microservice and you cannot afford to spend months working on a rewrite. Instead you need to take small steps. But small steps and keeping everything working may seem like a daunting approach. This hands-on will get you acquainted with several techniques and the right mindset that will allow you to make big changes in small steps.

This workshop will be mostly hands-on coding with some guidance and lots of useful discussion, allowing you to experience these techniques hands-on and share knowledge with the other participants. At the start of the workshop, you can choose to do it in Kotlin or Java.

As preparation, make sure you have a recent IntelliJ IDEA installed on your machine (community edition is sufficient).
