I always thought that my code was fine. I took my time naming things, wrote small classes/methods, and tried to use other Clean Code practices. But after a job interview with a technical coach, I was pointed toward Domain-Driven Design (DDD) and some other design topics. I could learn a lot from it, said the technical coach. And I did! Since then, I started noticing how much parts of DDD could help with my day-to-day job. I will take you with me on my learning journey of Domain-Driven Design, and how it helped me improve my code. We will touch upon themes like Ubiquitous Language, Supple Design, Bounded Contexts, and more. You can expect a talk with a lot of code examples and practical advice that you can use the next day.
