Raju has long been in the pursuit of hermeticism across the development stack by championing immutability during development (with languages like Clojure), deployment (leveraging tools like Docker and Kubernetes), and provisioning and configuration via code (toolkits like Ansible, Terraform, Packer, everything-as-code). Raju is also the author of JavaScript Next: Your Complete Guide to the New Features Introduced in JavaScript, Starting from ES6 to ES9, Apress, October 2019.
