SQL Server slow, unstable, poorly documented, or becoming too risky to manage? That is exactly where I help. I'm a senior Microsoft SQL Server DBA and Developer with nearly 20 years of experience helping businesses troubleshoot, stabilize, optimize, migrate, and maintain SQL Server environments across versions 2000 through 2022. My work covers production DBA support, performance tuning, T-SQL development, high availability, disaster recovery, Azure SQL, AWS RDS, reporting, ETL, security, and database architecture. I help clients solve real SQL Server problems without unnecessary complexity. Whether your queries are timing out, backups are questionable, SQL Agent jobs are failing, reports are slow, an upgrade is overdue, or nobody is fully confident in the recovery plan — I can assess the environment and move it in the right direction. WHAT I DELIVER ◾ Performance tuning — slow queries, execution plans, indexing, waits, blocking, deadlocks, parameter sniffing, Query Store analysis ◾ Production DBA support — backups, restores, DBCC checks, SQL Agent jobs, maintenance plans, monitoring, alerts, server health reviews ◾ High availability and disaster recovery — Always On Availability Groups, clustering, log shipping, replication, backup strategy, restore testing, RTO/RPO planning ◾ SQL Server development — stored procedures, views, functions, triggers, T-SQL cleanup, reporting queries, data logic troubleshooting ◾ Migrations and upgrades — version upgrades, server moves, cloud migrations, Azure SQL Database, Azure SQL Managed Instance, AWS RDS ◾ Reporting and ETL — SSRS, SSIS, data imports/exports, scheduled jobs, broken or slow reporting processes ◾ Security and compliance — permissions, least privilege access, SQL logins/users, auditing, encryption, documentation, PCI, STIG compliance ◾ Documentation and knowledge transfer — runbooks, handoff guides, diagrams, and practical recommendations your team can use PERFORMANCE & TROUBLESHOOTING Many clients bring me in when SQL Server is already under pressure. Common problems I fix: ◾ Slow applications caused by inefficient SQL queries ◾ Reports that time out or block production users ◾ High CPU, memory pressure, tempdb issues, or storage bottlenecks ◾ Blocking, deadlocks, and long-running transactions ◾ Poor or over-indexed databases ◾ SQL Agent job failures ◾ Backup chain confusion or restore uncertainty ◾ Availability Group, replication, or failover problems ◾ Legacy databases with little or no documentation I focus on finding the actual cause, explaining it in plain terms, and recommending fixes that are safe for production. HOW I WORK 1. Discovery — Review the environment, the problem, business impact, risks, and current configuration 2. Assessment — Identify performance, reliability, security, backup, and architecture issues 3. Plan — Prioritize the safest and highest-value fixes first 4. Implement — Make careful changes with rollback awareness and documentation 5. Validate — Confirm the issue is resolved using data, not guesswork 6.
