""Senior DevOps is about building reliable automated feedback loops between code commit and production observability. The interviewer is testing: Decoupling deployment from release, technical debt management.. I structure my answer around systematic triage first, root cause analysis second, and permanent remediation third.""

Production Solution & Architecture
Feature Flags allow developers to merge code to production but keep the feature hidden or disabled via a configuration toggle. This decouples the deployment of code from the business release of a feature and allows for safe canary rollouts (e.g., enable for 5% of users). Operational Risk: The main risk is Flag Debt. Over time, if old flags are not pruned, the codebase slowly turns into a labyrinth of fragmented if/else logic. This dramatically increases testing complexity (every flag doubles the number of possible system states). Forgotten flags accidentally flipped back on years later can cause catastrophic data corruption or bring down the application.
