About this gig

Is your ASP.NET Core app throwing errors, timing out or getting slower as data grows? I find the root cause and fix it properly, not with a workaround.


What I fix:

  • Runtime errors, exceptions and failing builds
  • Slow API endpoints and pages
  • Slow SQL Server queries, missing indexes and deadlocks
  • Memory leaks and high CPU usage
  • Entity Framework Core issues: N+1 queries, tracking, migrations
  • Broken deployments on Azure or IIS


How it works:

  1. Send me the error, logs or a short description of the problem
  2. I review it and confirm scope and price before you order
  3. I fix it, test it and explain what was wrong and how to avoid it


Supported: .NET Framework 4.x, .NET Core, .NET 6 to 10, C#, SQL Server, Entity Framework, Azure.
