I will fix, upgrade and deploy your asp net core, mvc or web forms application


Level 1
Gig Summary
About this gig
Is your ASP.NET application throwing errors, running slow or failing to deploy? I find the root cause, fix it properly and explain what changed.
I'm a full-stack .NET developer with 5+ years of experience, 40+ clients and 60+ projects delivered. I work with ASP.NET Core, MVC, Web Forms, C#, SQL Server, React and Next.js.
What I fix and build:
- Runtime errors, crashes and broken features
- Slow pages and SQL query performance
- Login, JWT, OAuth and Identity issues
- Upgrades from .NET Framework to .NET 8+
- Deployment to IIS, Azure or AWS
- API and third-party integrations, including OpenAI
How every order runs:
1. You share the issue, the code and steps to reproduce
2. I confirm scope and delivery date before I start
3. You get a progress update during the order
4. Delivery includes a short note: what was wrong, what I changed, how to test
Not sure which package fits? Send me the error message and I'll tell you honestly.
Bigger project or custom scope? Message me first and I'll send you a custom offer.

FAQ
What do you need from me to start?
Access to the code (Git repo or zip), the error message or steps to reproduce, your .NET version and where it is hosted. A database backup helps if the issue involves data.
What if the problem is bigger than my package?
I tell you before doing any extra work and we agree on the scope first. You never pay for work you didn't approve.
Do you work on older .NET Framework and Web Forms apps?
Yes. I maintain and fix legacy Web Forms and MVC apps and can plan an upgrade to modern ASP.NET Core when it makes sense.
Will you explain the fix?
Yes. Every delivery includes a short note on the cause, the change and how to test it.
Can you deploy the app after fixing it?
Yes, to IIS, Azure App Service or AWS. The Premium package includes deployment.
