Senior Microsoft SQL Server DBA | Production Performance Tuning Expert

Production SQL Server performance tuning is what I do every day. By the time most clients contact me, they've already spent time trying to understand the problem and need another set of experienced eyes on it. High CPU, blocking, deadlocks, query timeouts, long-running queries, and sudden performance regressions are the kinds of problems I spend most of my time investigating. I don't start by making changes. I start by understanding what's happening. Every production workload is different, so good performance tuning starts with identifying the real bottleneck before deciding what, if anything, needs to change. For the last 10+ years, I've focused on troubleshooting and optimizing SQL Server performance in production environments. I've worked with SQL Server 2008 through SQL Server 2025 across on-premises environments, Azure SQL Database, Azure SQL Managed Instance, and Amazon RDS for SQL Server. Many of my clients first contact me to solve a production SQL Server performance problem. Many continue working with me to help keep their SQL Server environments performing well as workloads grow. If you're dealing with a production SQL Server performance problem that's been difficult to diagnose, I'd be glad to take a look.
