About this gig
Legacy .NET Framework ASP.NET Core Migration Expert
Running an old .NET Framework application that's becoming a
liability? Outdated frameworks mean security vulnerabilities,
rising hosting costs, and developers who don't want to touch
legacy code. I help businesses modernize safely with zero
disruption to existing functionality.

- Full .NET Framework (4.x) to .NET 6/7/8 migration
- ASP.NET MVC ASP.NET Core MVC conversion
- Entity Framework EF Core migration
- Dependency Injection restructuring
- NuGet package compatibility audit & fixes
- Cross-platform readiness (Linux/Docker deployment)
- Full regression testing before handoff
WHY MODERNIZE:
2-3x better performance
Lower hosting costs (Linux-compatible)
Long-term Microsoft support & security patches
Easier to hire developers for (modern skillset)
MY PROCESS:
1. Codebase audit + migration roadmap (free with order)
2. Incremental migration with checkpoint testing
3. Full regression + performance testing
4. Deployment support & documentation handoff
️ IMPORTANT: Every legacy codebase is different in size and
complexity. Message me with your project details .

FAQ
Q: Will my application's functionality change after migration?
A: No — the goal is 100% functional parity. Same features, modern framework underneath.
Q: Do you need to see my code before quoting?
A: Yes, at minimum a project structure overview or sample controller, so I can give an accurate timeline and price.
Q: What if my project uses outdated/unsupported third-party libraries?
A: I'll identify modern, compatible alternatives and discuss the trade-offs with you before starting.
Q: Is my source code kept confidential?
A: Yes, I treat all client code as strictly confidential. I'm also happy to sign an NDA for enterprise projects.
Can you migrate WebForms applications too?
WebForms doesn't have a direct .NET Core equivalent, but I can help re-architect it to Blazor or Razor Pages — this is scoped separately as it's a bigger rewrite, not a straight migration.
