I will fix bugs and errors in your csharp dotnet application


About this gig
Your build fails, an endpoint returns 500, EF Core throws an exception you have never seen before, or something works locally but breaks in production. I find the cause and fix it.
WHAT I WORK WITH
C# and .NET 6/7/8/9/10, ASP.NET Core, Entity Framework Core, Web APIs, Blazor, SQL Server and PostgreSQL, Azure deployments.
HOW IT WORKS
1. Message me the error message or stack trace, the steps to reproduce it, and your .NET version.
2. I confirm I can help and you place the order.
3. You share the repository or the relevant files.
4. You get the fix plus a short explanation of what went wrong.
WHY ME
I am a software engineering student in the Netherlands, close to graduating, and I have been building .NET backends for years. I work fast, I explain what I changed instead of handing you a black box, and I will tell you honestly when a problem is bigger than a quick fix.
NOT INCLUDED
New features, full rewrites, .NET Framework below 4.8, or projects without a reproducible error.
Not sure if your issue fits? Send me a message first. I answer quickly and I will say no if I am not the right person for it.

FAQ
Why is it so cheap?
I am trying to get some reviews before I make the price more expensive, so get in while you can!
My deployement is not working, can you fix this?
Yes, I can help you set up a ci/cd pipeline aswell. Just shoot me a message!
Do you only do dotnet?
No, however my expertise is within dotnet. I am open to a lot of PHP and JavaScript frameworks aswell! Just shoot me a message.
What do you need acces to to fix this bug?
I will need acces to the file(s) where the bug occurs. So you can either send a zip or add me to a git and I will make a branch with the fixed code.
