Every conversation, since episode one.

In this episode of BEAM There, Done That, hosts explore what really happens when the high-level concurrency and fault-tolerance of Elixir meet the low-level performance and control of Rust. The conversation dives into interoperability patterns—NIFs, ports, and emerging tooling—and where each language shines when building real-world systems that need both resilience and raw speed. Joining the discussion are Florian Gilcher, Co-founder and Managing Director of Ferrous Systems and a key figure in Rust’s community, adoption, and safety-critical systems work, and Leandro Pereira, an Elixir developer behind high-performance, developer-focused tools like MDEx, Lumis, and BeaconCMS. Together, they unpack when to stay on the BEAM, when to reach for Rust, and how combining the two can unlock a powerful hybrid architecture without compromising safety or developer productivity.
