  • Review, optimize and refactor the existing database schema

    • Implement self-service interfaces for our product-teams to minimize operational workload for your team
    • Review database related changes from product-teams
    • Implement alerts and monitoring to prevent bad performance or a downtime on our database clusters
    • Reconfigure databases to fit the performance/security trade off suitable for a service
