In this 20-minute conference talk from Code BEAM Europe 2024, Dylan Blakemore explores the unexpected advantages of rebuilding tools when adopting a new programming language in an established organization. Discover how his team at Zappi transformed the challenge of lacking Elixir tooling into an opportunity by recreating their internal systems from scratch after transitioning from Ruby on Rails. Learn how this process not only led to Zappi's first open-source project but also helped team members develop into more well-rounded engineers. The presentation provides valuable insights for organizations considering language transitions and demonstrates why starting fresh with tooling can be beneficial rather than prohibitive.
