Modern collaboration methods such as event storming help to bring experts and developers together. "Domain modeling" goes one step further and enables joint work directly on the code. This workshop offers the opportunity to try it out using a practical example.

You will be assigned a PO who will explain the business aspects to you. First, we develop the big picture in event storming. We then model the domain in small groups using a type system. You can use TypeScript or Kotlin for this. We will enforce invariants already at compile time and our domain experts have the opportunity to give direct feedback on the code.

The aim of the workshop is not only to use the type system correctly for domain modeling, but also to practice communicating with POs, customers and other domain experts.
