What I'm looking for

I’m looking for a role where I can own database reliability end-to-end—HA/DR, performance tuning, and automation—across cloud environments, and continuously reduce downtime through proactive monitoring, incident handling, and smarter operational workflows.

I’m a Database Reliability Engineer with 5+ years of experience managing mission-critical SQL Server, PostgreSQL, and MySQL databases across airline, e-commerce, and telecom environments. I focus on high availability, performance tuning, and dependable operations, from production support to root cause analysis in both on-premises and cloud setups.

I’ve helped teams achieve measurable reliability outcomes—improving query execution time by up to 40% through execution plan analysis, indexing, deadlock resolution, statistics updates, and parameter tuning. I design and run HA/DR implementations such as Always On Availability Groups, failover clustering, replication, and Point-in-Time Recovery (PITR), while safeguarding data through backup and recovery health checks and recovery strategies.

I also automate operational workflows using PowerShell, Bash scripting, and Cron jobs to reduce manual effort and speed up incident resolution. Recently, I developed an AI-assisted DBA operations portal leveraging Claude AI to automate Level 1 database administration tasks, and I’ve supported cloud migrations across Azure, AWS, and GCP with minimal downtime and zero data loss.
