Developer Productivity Engineering at CERN
summary
CERN’s business computing group standardizes JVM projects for 80+ developers using templates, GitLab components, Vault for secrets and Argo CD for deployments, and measures results: a demo shows 75 tasks across 14 projects building in ~45s with 19 avoided tasks saving ~11s via a Gradle build cache fed by a remote build cache; dependency management uses version catalogs so Spring Boot upgrades hit one file; Sourcegraph, SonarQube and Vault integrate and the cache works across two machines in the demo.
