What I'm looking for

I’m looking to own database platforms—architecture, HA/DR, security, and performance—while partnering cross-functionally to modernize systems. I value automation, clear documentation, and meeting business targets with resilient, compliant solutions.

I’m a results-driven Senior Database Administrator with 19 years of IT experience and 14+ years focused on SQL Server administration. I own database architecture, administration, performance, security, and HA/DR end to end—delivering 99.99% uptime and translating business requirements into scalable SQL and NoSQL platforms across Pharma, Financial, and Banking domains.

I design and run high availability and disaster recovery using Always On availability groups, clustering, replication, and RDS Multi-AZ, while meeting RPO/RTO targets with minimal downtime. I improve performance through query tuning, indexing, and lock optimization, strengthen security with role-based access control, encryption, and auditing, and drive automation with PowerShell, Python, and T-SQL to save 12+ hours per cycle while keeping systems compliant and resilient.
