Keeping engineers effective is not a small task when you work at Meta’s scale. Many of the tools you take for granted simply break or become unbearably slow. Chandrika’s team looks after developer experience at Meta and takes a holistic approach that spans the editing experience (IDEs, editors), builds, continuous integration and even custom calendar tooling. Her team ensures that as new platforms, for instance AR/VR, and languages like Swift and Kotlin emerge, our infrastructure is ready. Got feedback?
