Advanced Functional Programming with Elixir: Model Behavior, Manage Complexity, and Maximize Maintainability

Get ready to manage crowds, adjust priorities, and keep everyone safe in FunPark, a place that never sits still. Your job is to model that complexity and build the systems that keep everything running smoothly, even as the business team is still figuring out what they want and the experts keep rewriting the rules.

Using core abstractions—equality, ordering, predicates, monoids, and monads—you'll break problems into small, composable pieces that are both well-behaved and easy to combine. Rather than getting bogged down in theory or formal proofs, you’ll dive into real-world Elixir—using protocols, structs, and pattern matching to express shared behavior across your domain. Along the way, you'll build the vocabulary and mental models you need to organize complex logic, supported by a production-ready open-source library you can use, extend, and explore in your own projects.

Whether you're an Elixir developer mastering functional programming or a functional programmer exploring Elixir, you'll discover how to write code that’s easier to reason about—and create systems that stay understandable, even as they grow.
