  • Harden NGDC environments with AVI/GSLB patterns (Prod1/Prod2) and BCP
  • execute DR failover runbooks and steady‑state capacity planning.
  • Publish steady‑state runbooks (deploy → certify → promote): DEV → UAT → MDEP‑Beta → MDEP‑GA / UCEP
  • define promotion criteria and risk exceptions.
  • Own endpoint product ionization via Apigee (AI Gateway)—authN/Z, rate limiting, API SLAs, versioning/deprecation and SDK generation for internal consumers.
  • Embed observability/evaluations with Overwatch + Arize: prompt/agent/tool tracing, SLO dashboards, alerting, and data‑retention/export workflows.
