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. US military veteran. I work remotely on consulting engagements. HOW TO START Use Upwork Messages to tell me what changed, when it started, and what business process is affected. If you have an execution plan or error message, include it. I will tell you the next useful step.
