Have you ever opened a legacy code file and had the irresistible urge to close your IDE? Don’t worry, we’ve all been there! But what if we told you that with a few simple rules, this code can become more readable, maintainable and even pleasant to develop?

Object-oriented programming is “easy to learn, hard to master”. In this session, we take you into a live pair programming session, where we will apply Object Calisthenics: 9 rules designed to strengthen your code and make it more modular. Starting from a legacy base in Kotlin, we will do an incremental refactoring together to transform it into robust, elegant and easy to maintain code.

What to expect: fun, refactoring, and concrete tips, with Kent Beck's maxim in mind: “Make the change easy, then make the easy change.”

You will leave this session with an irrepressible desire to reopen your IDE and improve your codebase.
