A Day in the Life

Morning starts with reviewing platform adoption metrics and reading developer feedback from the internal survey. You work on building a new Backstage plugin that gives teams visibility into their service health. After lunch, you pair with a product team to debug a deployment issue, turning the root cause into a platform improvement. You end the day writing an RFC for a new self-service networking feature.
