This book is for anyone who has an interest in CQRS/ES and Elixir.

About the Author

Ben
Ben

Ben Smith is a full stack software engineer with a focus on the design, build, and deployment of intuitive and performant web applications.

Ben follows the domain-driven design approach to building software. He advocates using the Command Query Responsibility Segregation (CQRS) pattern to build the core business software. This approach allows a clean separation of the domain model for accepting command-based write operations, and a read-only query model. Both sides can be independently scaled: the development team and the physical deployment to the production environment.

Ben is enthusiastically using Elixir, Erlang/OTP, and Phoenix to build scalable web applications that respond in microseconds.
