I will modernize and upgrade your legacy dotnet application to dotnet core

Is your legacy .NET app holding your business back?

I'm a full stack developer with 20+ years of experience modernizing legacy applications porting old codebases to modern .NET, wrapping legacy C++ libraries, and rebuilding monoliths as clean microservice APIs. I currently build enterprise software for a major U.S. airline.

What I modernize:

• .NET Framework .NET 8 migrations
• Old WebForms/ASP classic apps modern web apps
• Legacy databases and stored procedures clean SQL + APIs
• Untested code tested, documented, maintainable code

How it works: every project starts with an audit. You get a written assessment of your codebase risks, dependencies, and a prioritized roadmap before any migration begins. No surprises, no "we found something" invoices.

Why me? Modernization is where inexperience gets expensive. I've done these migrations in production environments where downtime wasn't an option. Your app gets that same discipline.

Before you order: message me with a short description of your app, its age, and tech stack. I'll confirm scope before you spend a dime.
