What I'm looking for

I seek senior technical roles building scalable, highly available database and data warehouse solutions, mentoring teams, and driving cloud migration and performance improvements in collaborative environments.

I am a results-driven SQL Database Architect with 33 years of experience in database administration, development, and enterprise architecture. I specialize in designing and optimizing mission-critical SQL Server environments, data warehouses, and ETL/BI solutions to support high-volume e-commerce and enterprise platforms.

At enterprise and cloud levels I have led performance optimization initiatives using Query Store, Extended Events, and memory-optimized tables, implemented Azure cloud architecture and disaster recovery strategies, and created automated monitoring and health-check systems. I mentor teams, establish database development standards, and drive cost-optimized, highly available infrastructures.

My technical breadth includes SQL Server (2005–2022), Azure SQL, SSIS/SSAS/SSRS, MySQL and Sybase, HA/DR solutions, and performance tuning. I hold Microsoft certifications in SQL administration, provisioning, BI, and querying, and I bring determination, adaptability, and a collaborative leadership style to deliver measurable improvements.
