I will fix bugs and performance issues in dot net web app
Ali
About this gig
Is your Dot Net web application showing errors, behaving unexpectedly, or running slower than it should?
I'm a software developer with 7+ years of professional software development experience, working extensively with C#, Dot Net and application development across web and other software platforms.
I can Diagnose and Fix issues in existing:
- ASP.NET / ASP.NET Core applications
- C# and Dot Net applications
- Web APIs and integrations
- Entity Framework / EF Core
- SQL Server and database queries
- Angular / React frontends connected to Dot Net
- Authentication and authorization
- Application performance and slow APIs
My approach is to identify the underlying cause, implement the appropriate fix, and test the result rather than simply applying a temporary workaround.
If your application has a bug, error, integration problem or performance issue, send me the details before ordering. I'll review the problem and help determine the best solution.
NOTE: Please contact me before ordering for complex or production-critical issues so I can review the problem and provide an accurate offer.
