How Uber Engineering Verifies Data at Runtime with the Annotations You Already Use

Uber’s hypergrowth forces our developers to engineer stability into our apps using resourceful techniques.

Since then, the community has developed better ways to create scalable, data-driven interfaces. jQuery’s “render and modify” approach is straightforward, but it’s prone to falling out of sync with the underlying model.
