About this gig

Something in your C# or .NET project throws an error, returns the wrong data, or stopped working after an update. I find the cause and fix it.


I work with:

- ASP.NET Core and ASP.NET MVC applications

- Web API endpoints returning wrong results or error codes

- Entity Framework issues: migrations, relationships, slow or incorrect queries

- MS SQL queries and stored procedures

- Console and desktop C# applications


How I work:

1. You send the code and the exact error or wrong behaviour

2. I reproduce it and find the actual cause, not just the symptom

3. I fix it and explain in plain language what was wrong and what I changed


You get the fixed code plus a short written explanation. If I cannot reproduce your problem with what you send me, I tell you before you order rather than after.


Message me with the error message before ordering and I will tell you which package fits.

I am a software developer working mainly with C# and .NET. I build REST APIs with ASP.NET Core, design and optimise MS SQL databases with Entity Framework, and set up CI/CD pipelines for deployment. I also work with JavaScript, HTML and CSS on the web side. I worked as a software instructor teaching C#, MS SQL and ASP.NET, so I explain what I changed and why in plain language. You are never handed code you cannot maintain. Tell me what you are building and I will say honestly whether I am the right fit.
