SQL Server slow? SQL Server Agent jobs failing? Planning an Azure SQL migration and need to know what will break? I diagnose the problem, explain it in plain English, and give you a prioritized plan. I have worked with Microsoft SQL Server for more than 20 years. I am Expert-Vetted on Upwork, with a 100% Job Success Score and 5.0 feedback across eight jobs. Most engagements begin with a focused diagnostic. We meet through Upwork, I review what is actually happening, and you get a straight answer. The cause may be a query, an index, configuration, a failed job, or an architecture decision. If it is a small fix, I will say so. If it needs a larger effort, I will define that work before you commit. WHAT I HANDLE - Slow queries and execution plans - SQL Server Agent job failures - Index, memory, tempdb, and configuration problems - SSIS packages failing after environment changes - Reports with inconsistent or untrusted results - Azure SQL migration readiness and execution Beyond database rescue, I build and modernize line-of-business applications in C#, ASP.NET Core, Blazor, and Azure. I also work on AI features that must operate against existing SQL Server data and permissions. That work starts with the business question, access rules, and a clear way to verify the result. BACKGROUND I have run Coding Innovations since 2009. My work includes healthcare, retail, supply chain, and automotive systems. Before that, I was a lead developer and architect at Perot Systems (Dell). Credentials: MCSA SQL 2016 Database Development, MCDBA for SQL Server 2000, MCAD (.NET), Certified ScrumMaster.
