About Teja Kosaraju

I’m a Senior SQL Server & Cloud Database Engineer with 9+ years of experience managing mission-critical production environments across financial and insurance enterprises. I specialize in building highly available, automated, and performance-optimized database platforms across on-prem and cloud infrastructures including Azure SQL, AWS RDS, and SQL Server clusters.My expertise includes designing HA/DR architectures (AlwaysOn AG, Failover Clustering, replication, geo-redundant cloud failover) delivering sub-10-minute recovery objectives and near-zero data loss. I regularly troubleshoot critical production incidents, tune high-concurrency OLTP workloads, and improve system throughput using execution plan analysis, Query Store diagnostics, and advanced indexing strategies.I strongly focus on automation and DevOps-driven database delivery. I’ve implemented CI/CD database deployments using Azure DevOps and Jenkins, created PowerShell-based provisioning frameworks, and built automated restore validation pipelines — reducing manual operational effort by over 50% while improving deployment reliability.I also implement enterprise-grade security and compliance including TDE encryption, RBAC frameworks, and audit controls supporting SOX/PCI regulated environments with zero critical audit findings.
