• Design MCP/tool access with clear permissioning, audit logs, least-privilege access, PII controls, and failure handling.

• Support production issue investigation using logs, metrics, traces, database checks, monitoring tools, and release evidence.

• Work with Product, QA, Mobile, DevOps, Data, IS, and Support to diagnose and resolve issues quickly.
