What I'm looking for

I’m looking for a team where I can own SQL Server and cloud database architecture end-to-end—driving HA/DR, security compliance, automation, and performance tuning with strong CI/CD and cross-functional collaboration.

I’m a database infrastructure leader with 19 years of enterprise IT experience, including 14+ years specializing in SQL Server architecture, administration, and cloud database operations. I focus on end-to-end ownership across database security, performance engineering, and cloud transformation.

I’ve delivered 99.99% uptime in production through Always On Availability Groups, multi-node clustering, and HA/DR strategies spanning on-premises, AWS RDS, and Azure SQL. I lead zero-risk SQL Server migrations and continuous improvements that reduce downtime and strengthen reliability.

My recent impact includes a 50% reduction in production system downtime by executing zero-risk migrations from 2012/2014 to 2019/2022 in live financial services environments. I also generated $695 in monthly AWS savings by right-sizing infrastructure tiers and eliminating redundant backup storage.

I’m especially proud of operational automation: I engineered PowerShell-driven solutions for large-scale (12 TB) database refresh processes, reclaiming 12 hours per cycle and reducing manual DBA intervention by 40% through DR simulations and patch deployment pipelines. I collaborate across teams in Agile settings to deliver CI/CD-aligned, secure, and observable database releases.
