What I'm looking for

I seek a SQL Server DBA role focused on high-availability, disaster recovery, performance tuning, and automation, in a collaborative, ITIL-driven team with opportunities to lead DR/HA initiatives.

I am a SQL Server Database Administrator with 6.7 years of hands-on experience, specializing in installation, configuration, upgrades, and patch management across SQL Server 2008R2 through 2022. I have implemented high-availability and disaster recovery solutions including Log Shipping, Mirroring, AlwaysOn, and failover clustering, and supported backups, restores, replication, and proactive monitoring.

I focus on database security, performance tuning, index maintenance, job scheduling, and automation with PowerShell while following ITIL practices and supporting shift-based operations. I collaborate with developers, system administrators, and business stakeholders to align DBA activities with business requirements and to deliver reliable, well-documented database services.
