What programming languages does Nubank use?

Public signals support Clojure, Scala, Flutter/Dart, plus platform tooling around AWS and Kubernetes.

Does Nubank use AWS, GCP, or Azure?

AWS is publicly signaled through AWS CloudFormation/Nimbus case material; Kubernetes is also publicly signaled through CNCF coverage.

How is Nubank's tech stack detected?

This stack is directional, based on public engineering posts, developer docs, job descriptions, and vendor documentation. It should be validated in discovery before treating a tool as installed across the company.

What tech stack does Nubank use?

Nubank’s stack is detected from its engineering blog and public cloud-native case studies. High-confidence signals include Clojure for production services, Kafka for asynchronous communication, Datomic for high-value business data, Scala for analytics, Flutter for mobile, AWS CloudFormation/Nimbus, and Kubernetes/canary deployments.

What does Nubank use on the backend and infrastructure?

Nubank’s engineering blog explicitly describes Clojure for production services, Kafka for async communication, Datomic for high-value business data, Scala for analytics, and Flutter for mobile. AWS has documented Nubank using a Clojure tool called Nimbus to manage CloudFormation.

What does Nubank use on the frontend, data, or GTM tooling?

Frontend and mobile experiences are central because Nubank is branchless. Public stack signals emphasize Flutter for mobile and strong internal tooling around deployments, data, and developer experience.

What Nubank's stack means if you sell to them

Nubank’s stack implies a high bar for functional programming, data correctness, regulated reliability, and cloud automation. Strong pitches include Clojure/Datomic interoperability, Kubernetes reliability, credit-risk data, AI customer service, compliance automation, and mobile performance.
