Database Administrator at DEFI Solutions, architecting SQL Server high availability across Azure and AWS for loan origination workloads.

United States

Message

At DEFI Solutions, I provision and support Azure SQL Managed Instance, Azure SQL Database, SQL Server on AWS EC2, and Amazon RDS for loan origination workloads. I architected Always On and Distributed Availability Groups across clusters and regions, and run failover drills to validate recovery targets.

At Truist Bank, I administered SQL Server and PostgreSQL across on-premises, Azure, and AWS environments supporting core banking applications. I migrated SQL Server workloads to PostgreSQL, improved throughput on critical banking systems, and mentored junior DBAs; earlier, at Mastercard, I maintained 99.9% uptime for payment processing environments.
