"It took one tense meeting to realize we were grabbing knives before deciding what to cook. So we paused and asked: What journeys should a dev complete without opening a Slack thread? What needs to be self-served? What's our "platform MVP"? We weren't building a cathedral. We were starting with one dish: deploying a backend service safely. We chose principles first: ✅ GitOps for consistency ✅ IaC for transparency ✅ Guardrails, not gates The tech came after."
"We weren't building a cathedral. We were starting with one dish: deploying a backend service safely. The dish we picked? "New backend service → CI → deploy → rollback" Sounds simple. Wasn't. Some devs were skeptical. "Isn't this just another infra ticket wrapped in a CLI?" But we mapped every touchpoint: GitHub push triggers GitHub Actions → container build ArgoCD syncs the Helm chart to Kubernetes Sentry, Prometheus, Grafana wired in"
Platform engineers started by defining principles before choosing tooling. They prioritized GitOps for consistency, Infrastructure as Code for transparency, and guardrails instead of gates. The team selected a narrow, end-to-end golden path: creating a new backend service through CI, deployment, and rollback. The path mapped each touchpoint from GitHub pushes triggering GitHub Actions to container builds, ArgoCD syncing Helm charts to Kubernetes, and monitoring via Sentry, Prometheus, and Grafana. The approach emphasized self-service journeys that developers can complete without Slack, focused scope for a platform MVP, and tools chosen to implement agreed principles.
