I will fix, maintain and modernize legacy vb net or web forms app
About this gig
Still running a VB.NET or ASP.NET Web Forms application that nobody
wants to touch?
I've spent 11.5 years working on exactly this kind of software
business-critical Microsoft stack applications that companies depend
on every day. C#, VB.NET, ASP.NET, Web Forms, SQL Server and Azure.
Most developers avoid legacy .NET. I don't. I understand why these
systems were built the way they were, and how to change them without
breaking the parts that are quietly holding your business together.
WHAT I CAN HELP WITH
- Fixing bugs in old VB.NET / Web Forms applications
- Adding features to systems the original developer left behind
- Upgrading old .NET Framework versions
- Preparing a legacy app for migration to .NET Core / .NET 8
- SQL Server performance and query problems
- Getting an inherited codebase documented and understood
HOW I WORK
You'll always get a written explanation of what I found, what I
changed and why not just a zip file back. Your code is treated
as confidential.
Not sure which package you need? Message me first with a short
description of your app and I'll tell you honestly whether I can help.

FAQ
Can you work on an app I didn't build?
Yes — that's most of what I do. Inherited and undocumented codebases are normal for this kind of work.
Can you migrate my VB.NET app to C# or .NET 8?
A full migration is usually beyond a single Fiverr order, but I can assess the app, tell you what's involved and do the preparation work. Message me and I'll be straight with you about scope.
Will you sign an NDA?
Yes, happy to
My app is really old — is it too far gone?
Probably not. Send me the details and I'll tell you honestly.
