Natnael Sertse

I am a Senior Database Administrator with over a decade of experience managing enterprise SQL Server environments across finance, airlines, healthcare, and manufacturing. I specialize in high availability, disaster recovery, performance tuning, and secure migrations to AWS and Azure, and I automate routine operations with PowerShell and T-SQL.

I have led large migrations to AWS RDS, RDS-Custom, and Azure SQL Managed Instance, consolidated legacy servers, and implemented Always On Availability Groups and multi-node Windows Failover Clustering to achieve strong uptime and disaster recovery. My work has delivered measurable cost savings, reduced hardware footprints, and improved query performance through partitioning, archiving, and index optimization.

I enforce security and compliance controls, integrate monitoring into ITSM workflows, and build real-time dashboards and automated maintenance pipelines to reduce manual effort and accelerate incident response. I am results-driven, collaboration-focused, and committed to supporting mission-critical applications with resilient, optimized database solutions.
