Description
Design, implement, and review feature flags and gradual rollouts — flag types (release, experiment, ops kill switch, permission/entitlement), server-side evaluation in Next.js (Vercel Flags SDK, OpenFeature, PostHog, LaunchDarkly, GrowthBook, Statsig, or DB-backed), sticky percentage rollouts keyed by user ID, avoiding flicker and caching bugs, mobile remote config with safe defaults, flags in tests, ownership and expiry, and cleaning up stale flags. Use whenever the user wants to ship behind a flag, do a gradual or percentage rollout, add a kill switch, run an A/B test, or reviews code containing flag checks.
