I have managed hundreds of databases across multiple data centers, led large migration projects including moving over 50 databases from on-premises to Azure, and supported VLDBs with capacity planning and 24x7 production support.

My technical strengths include back up and restore, security, performance tuning, query optimization, Always On availability groups, clustering, log shipping, replication, TDE, dynamic data masking, and tools such as Query Store, Extended Events, DTA, and SQL Profiler.
