Welcome back to the Elixir Wizards podcast! In this episode, we will be continuing our conversation on the theme of adopting elixir, and our great guest for today is Jason Axelson! Jason is a back-end developer for a mixed reality studio called Animal Repair Shop and has also made some significant contributions to the Elixir Language Server project. We kick off our conversation with Jason hearing about his programming journey and then dive into the event chat service app he helped build using Elixir while he was working at Hobnob. From there, we talk about some of his aha moments while learning Elixir and some of his favorite features about the language which he is putting to use building out the back end for Animal Repair Shop. Next, we turn our attention to Elixir Language Server and Jason weighs in on the IDE type features it offers, why he got started as a collaborator on the project, and some of their challenges in the field of shared governance. Wrapping up for today, Jason makes a few suggestions for how devs who love Elixir can convince their teams to adopt it as a more mainstream option. Tune in for a great chat on the topic of adopting Elixir!
