• Design replica set and sharded cluster topologies tailored to workload (R/W patterns, data growth, latency, multi-AZ/region).
• Schema and index design aligned with document modeling patterns (subdocuments, bucketization, extended reference, outlier pattern).
• Capacity planning (IOPS/CPU/RAM/Storage), performance tuning (indexes, query plans, connection pools, WT cache).
• Backup/restore strategy design.
• Security hardening: RBAC, client certs/TLS, encryption-at-rest (KMIP/KMS), auditing, least-privilege, IP allow lists/NSGs, CIS benchmarks.
• Observability: metrics, logs, and tracing integrations (Mongo
  
  DB exporters/agents).
• Release management & lifecycle: rolling upgrades, feature compatibility versions (FCV), patching cadence, maintenance windows.

• Build idempotent Ansible roles and collections-based playbooks for provisioning:
  • OS hardening, users, packages, ulimits, sysctl

    DB install, config (mongod.conf), TLS, replica sets, config servers, mongos, sharding
  • User creation (app/admin), roles, indexes, parameters
  • Rolling upgrades and patching
• Drift detection & remediation, config guardrails, and change safety (serial/rolling strategies, pre-checks, post-verify).
