Modular Design in Elixir

Modular design is a great way to reduce complexity in software. In the Elixir ecosystem, the discussion around this topic has been energised by the introduction of Phoenix Contexts some time ago. Yet, coming up with good module boundaries is really hard and we lack ideas on how to do this well. Maciej will show a few techniques to ensue code is much easier to understand, test, and modify. After the talk, attendees will have some concrete techniques to design new features or improve existing codebases.

Objectives Show how to tackle designing modules based on behaviour. Focus on a step-by-step approach, without changing the entire architecture.

Audience Developers who work on systems with complex domain logic and would like to simplify them.
