Chi sono
SQL Server running slow, blocking users, timing out, or affecting production? I diagnose SQL Server performance problems, identify the likely root cause, and provide clear, practical remediation. I bring 30 years of IT experience, including senior T-SQL development, performance tuning, L3 production support, and root-cause analysis in high-volume environments. I can investigate slow queries, stored procedures, blocking, deadlocks, execution plans, indexing issues, and performance regressions. Choose the service level that matches the depth of investigation and remediation you need.
