I will fix your csharp, dotnet, asp net core, blazor or API bugs
Hernan A.
About this gig
I will debug and fix bugs in your C#, .NET, ASP.NET Core, Blazor, Web API, or backend application.
If your app is crashing, showing errors, failing after deployment, breaking API calls, or having database/authentication issues, I can help you investigate the problem and move forward.
I can help with:
- C# and .NET errors
- ASP.NET Core issues
- Blazor Server or WebAssembly bugs
- Web API problems
- Backend logic bugs
- Database or Entity Framework issues
- Authentication bugs
- Build or compilation errors
- Broken features
- Basic deployment-related issues
- Root-cause analysis
Depending on the package, you can receive bug investigation, a code fix, root-cause explanation, testing notes, and suggestions if the issue is bigger than expected.
Please send a short problem description, error messages or screenshots, steps to reproduce it, relevant code or repository access, and recent changes that may have caused the issue.
Important: debugging depends on access, project size, environment, and the real cause. Some issues may require a custom offer.
Please contact me before ordering so I can review the issue and confirm the best package. I can communicate in English or Spanish.

FAQ
Do I need to contact you before placing an order?
Yes, please contact me first. Debugging depends on the project, the error and the codebase size, so I need to review the issue before confirming the best package.
What do you need to start working?
I need a short description of the issue, error messages or screenshots, steps to reproduce the problem, and access to the relevant code or repository.
Can you fix any bug?
I will always investigate the issue carefully, but some bugs may depend on third-party services, missing access, broken environments or larger architecture problems. I will explain my findings clearly before making changes.
Do you work with Blazor?
Yes. I can help with Blazor Server, Blazor WebAssembly, components, data flow, API calls, rendering issues, and related .NET problems.
Do you work with ASP.NET Core Web API?
Yes. I can help with controllers, endpoints, API logic, dependency injection, Entity Framework, database calls, authentication issues, and backend bugs.
Will you explain what was wrong?
Yes. I include a clear explanation of the bug and the solution so you can understand what changed.
Can you work on large or complex projects?
Yes, but complex issues may require a custom offer after reviewing the code and problem. Please contact me first so I can estimate the scope correctly.
Can you help if I only have an error message?
Yes, but I will usually need the relevant code and steps to reproduce the issue before I can fix it properly.
