This week’s podcast features a chat with Vitor Olivier. Vitor is a partner at NuBank (a technology-centric bank in Brazil). This podcast hits on topics from several of Nubank’s recent QCon talks and includes things like: Nubank’s stack, functional programming, event sourcing, defining service boundaries, recommendations on reasoning about services, tips (or tweaks) on the second iteration of their initial architecture and more.

Why listen to this podcast:

- Property-based testing and Schemas (or Clojure.Spec)are complementary.

- Clojure’s functional nature and Datomic’s features are a match for Nubank’s requirements.

- A (micro)service needs to be able to create the full representation of the core feature it’s handling.

- GraphQL is useful to abstract away the distributed system complexity from the mobile (or frontend) developers.

- Nubank’s uses a combination of monitoring and sanity checks in real time at various level to keep systems consistent.

- Once an invariant is broken, the system will try to fix it automatically.
