I will modernize your windows desktop app with apis, cloud, or a web UI


About this gig
Your desktop app still works but it's stuck in the past. Let's fix that without a risky rewrite.
Full rewrites fail more often than they succeed. The smarter path is incremental modernization: keep the desktop app your business runs on, and extend it step by step into the modern world.
I'm a US-based software engineer with a rare combination: deep legacy .NET desktop experience (WinForms/WPF) and modern web development (React, .NET Web APIs). That means I can bridge both worlds most freelancers can only do one.
Modernization services:
- Wrap your desktop app's logic in a REST API so other systems can use it
- Sync your desktop database to the cloud (Azure, AWS, or SQL hosting)
- Build a React web dashboard or mobile companion view of your desktop data
- Migrate screens incrementally from WinForms/WPF to web no big-bang rewrite
- Upgrade .NET Framework apps to modern .NET
- Add automatic updates, installers, and modern deployment
Every project starts with a roadmap. My Basic package is a modernization assessment: I review your app and deliver a phased plan with realistic costs, so you can modernize at the pace your budget allows.

FAQ
Should we just rewrite the whole app?
Usually not — rewrites are expensive and risky. I'll give you an honest recommendation in the assessment; sometimes a rewrite is right, and I'll tell you if so.
Can our desktop app and a new web app run side by side?
Yes — that's the core of incremental migration, and it's exactly what I design for. There are obviously special exceptions.
What cloud platforms do you work with?
Azure is the natural fit for .NET, but I also work with AWS and standard SQL hosting.
