What does Expedia Group use on the backend and infrastructure?

Public signals point to a hybrid enterprise environment with Java, Scala, AWS, Kubernetes. For a company of this scale, legacy systems, vendor platforms, APIs, identity, security, network reliability, and integration governance matter as much as any single language or cloud provider.

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

Detected front-end, data, and commercial signals include JavaScript, React, Python, Kafka, iOS and Android. These signals are useful for integration planning, but they should be validated during discovery because public stack indexes do not expose all internal systems.

What Expedia Group's stack means if you sell to them

The best pitch is integration-aware. Sellers should show how they fit with identity, data warehouse, APIs, observability, mobile surfaces, security review, procurement controls, and the operational systems that run the business, while being clear about displacement versus augmentation.
