summary
Company migrates from GitOps booleans to an OpenFeature stack using flagd evaluation engine, custom DB and UI, OpenFeature SDKs (Java and React), gRPC flag-sync and OpenTelemetry for observability. Metrics: 2,300 feature flags with ~700 unused in 6 months and ~1,200 unused in 2 years; adoption reaches ~80 teams and tens of thousands of evaluations (60,000 in dev). Latency: backend <1ms, frontend ~20ms. A production incident from oversized numeric flags causes 500s and blocked rendering, prompting timeouts, edge-case handling, and safer defaults; results: smoother rollouts and growing experimentation.
