Hire the Best Microsoft SQL Server Developers
in India

SQL Server performance issues in production environments can be difficult to diagnose and often affect application reliability. I help diagnose and resolve SQL Server performance problems safely — without risky changes or unnecessary downtime. Common issues I solve: - High CPU usage or SOS_SCHEDULER_YIELD waits - Query timeouts during peak hours - Blocking chains and long-running transactions - Deadlocks impacting application stability - Slow queries and inefficient stored procedures I’m Kundan, a Senior SQL Server DBA specializing in performance tuning, troubleshooting, and stability improvements. I work with SQL Server environments that support mission-critical workloads and require reliable and predictable performance. Most of my work involves troubleshooting live production SQL Server environments where performance issues must be diagnosed quickly and resolved safely, with changes approached carefully after understanding the root cause. Common root causes I address: - Misconfigured SQL Server or database settings - Inefficient isolation levels - Missing or poorly designed indexes - Outdated or inaccurate statistics - Non-SARGable predicates - Parameter sniffing and parameter sensitivity issues - NULL value parameters or optional parameters My focus is not just fixing immediate symptoms. I identify root causes, prevent recurring issues, and help systems continue to perform reliably as workloads grow — reducing production incidents and improving overall reliability. I regularly support high-availability SQL Server environments where uptime and consistent performance are critical. Experience & Platforms With 10+ years of hands-on experience, I’ve worked extensively with SQL Server versions from 2008 through 2025, including: - SQL Server (on-premises) - Azure SQL Database - Azure SQL Managed Instance - Amazon RDS for SQL Server I combine proven optimization techniques with modern SQL Server capabilities such as: - New Cardinality Estimator - Columnstore Indexes - Accelerated Database Recovery - Optimized Locking - Query Store - Intelligent Query Processing to resolve complex performance challenges efficiently. If your SQL Server environment is slow, unstable, or difficult to scale, I can help restore performance and keep it running smoothly. P.S. Most clients contact me when their SQL Server becomes slow during peak usage or starts causing timeouts in production.

Hi There, I’d love to schedule a quick 10-minute conversation to demonstrate my SQL Server expertise (10+ years), flexibility with work timings, and cost-efficient employment. I can also share insights on my past work and how I communicate effectively with clients. Let me know a time that works for you—I’ll keep it brief and impactful! Best, Miraj Sen.
