I am Sagheer Ahmed, a SQL Server DBA with over 25 years of experience managing enterprise SQL Server environments.
My technical journey started long before SQL Server became what it is today. I still remember when the fastest personal computers ran at 4.77 MHz, and people working with dBASE II and dBASE III were considered very high tech. That was a different time, but it taught me something important: good systems are built by people who understand the details, not just the tools.
Over the years I have worked with hundreds of SQL Server instances, built automation with PowerShell and DBATools, supported Always On Availability Groups and failover clusters, and spent many nights troubleshooting real production problems. Some of the best lessons came during difficult incidents, when the answer had to be correct and there was no room for guessing.
I am not a developer. I am a DBA who automates. There is a difference.
Much of my work has been in enterprise and federal environments, including systems supporting defense, aviation, justice, and public-sector operations. Those environments teach discipline. You learn to verify, document, automate carefully, and respect the impact of every change.
Most of what I know was learned the hard way. After years of solving the same kinds of problems and rebuilding the same kinds of tools, I decided to start sharing. If something here saves you time, gives you a better troubleshooting path, or helps you get through a bad on-call night, then this site is doing its job.
What you will find here:
- SQL Server troubleshooting and diagnostics
- PowerShell automation for DBAs
- Always On, backup, performance, and operational patterns
- Tools and scripts built from real DBA work
- Practical lessons that work at scale, not just in tutorials
