Many organizations take an incremental approach when adopting Elixir, preferring to pick up its nuances by using it to work on non-essential projects. But not Change.org. Today we speak with Change.org Director of Engineering John Mertens about how his company adopted Elixir to create a business-critical app that handles over a billion emails per month. From building webpages on GeoCities to working as an IT intern at an Iowan prison, we open our conversation by exploring John’s coding background. After chatting about his first Elixir project, we dive into Change.org’s process in adopting Elixir. As John shares his insights into successfully integrating Elixir into your tech stack, he highlights the benefits provided by the language. Later, John discusses the advantages of event-driven architecture and how this structure makes it easier for teams to access and analyze data, while also making it easier to add product features. We wrap up this episode with John highlighting his user-centered approach to coding. Join us to hear John’s lessons on making the leap and adopting Elixir in large organizations.
