2018

• Building beautiful systems with Phoenix contexts - Learn about Phoenix contexts from their origins in domain-driven design and how they help you to organise an Elixir application by providing rules around communication, boundary enforcement and testing. [ [slides](https://speakerdeck.com/andrewhao/building-beautiful-systems-with-phoenix-contexts-and-ddd) ]
• CQRS and Event Sourcing - A look into what Event Sourcing and Command Query Responsibility Segregation are and how they fit together, followed by a tutorial on how to implement an application using these concepts with Commanded (a framework for Elixir).
• Event-driven architectures in Elixir - Learn how you can improve your architecture and reduce coupling by using events. [ [slides](http://s3.amazonaws.com/erlang-conferences-production/media/files/000/000/875/original/Maciej_Kaszubowski_-_Event-driven_architectures_in_Elixir.pdf) ]
• Event Sourcing in Elixir - In this talk, Pedro quickly introduces Event Sourcing and CQRS, but the main part is about [FootBroker](https://footbroker.tk), an online soccer fantasy game that it is running in production in a beta stage, and has its main pieces using Event Sourcing and CQRS patterns.

2019

• An event-driven approach to building Elixir applications - We experience the real world by reacting to events that have occurred, what if we modelled our Elixir applications in the same way? [ [slides](https://10consulting.com/2019/07/18/event-driven-elixir-applications/) ]
• Building Event Sourced Apps - Instead of defining a global data model that fits all of your use cases think about the things your system does. Record the events that occur and then build multiple data models that fit your individual use cases.
• CQRS/ES & Elixir - An introduction to the CQRS/ES architecture pattern and how to implement it in your application in Elixir with the Commanded framework.
• Event sourcing in practice - Using Elixir to build event-driven applications - Practical example of event sourcing in Elixir.

• Elixir + CQRS - Architecting for Availability, Operability, and Maintainability At PagerDuty - This talk looks at the service that powers PagerDuty’s timeline entries, a critical component for understanding what happens during an incident and covers how the service is architected for Command Query Responsibility Segregation and the benefits of those choices.
