- Design schemas and data models for search, caching, and graph-based use cases.
- Tune query performance and indexing strategies to meet SLAs for critical production systems.
- Automate deployment, scaling, and monitoring using DevOps tools (e.g., Terraform, Ansible, Docker, Kubernetes).
- Troubleshoot and resolve issues in real-time for revenue-impacting systems.
- Implement monitoring and alerting (e.g., CloudWatch, Prometheus) to detect performance issues.
- Ensure security and compliance with encryption and access controls (IAM, VPC).
