- Collaborate with API team on efficient data access patterns, query optimization, and caching strategies for activation endpoints
- Partner with Ingestion team on high-throughput write patterns, batch loading strategies, and schema evolution without downtime
- Design backup, point-in-time recovery, and disaster recovery procedures for critical user profile data
- Troubleshoot production storage issues including performance degradation, hot-spotting, lock contention, and capacity constraints
- Work with SRE teams on capacity planning, autoscaling strategies, cost optimization, and infrastructure efficiency
- Implement cache invalidation strategies, cache warming, and distributed caching patterns for consistent data access
- Create comprehensive documentation for storage architecture, operational runbooks, disaster recovery procedures, and on-call playbooks
