FAQ
Will the migration cause any downtime for my users?
My priority is a zero-downtime transition. I use side-by-side deployment strategies to ensure your current site remains live while the new .NET 8 / Angular 21 modules are phased in.
Do I need to provide the full source code?
Yes. To perform a reliable upgrade, I’ll need access to your GitHub/GitLab repository or a ZIP of the current project files. All code is handled with strict confidentiality.
What if my legacy app uses a library that is no longer supported?
I perform a dependency audit first. If a library is obsolete, I’ll replace it with a modern, high-performance equivalent (e.g., swapping AutoMapper for Mapster) included in the service.
Is your work SEO-friendly?
Absolutely. I specialize in fixing routing issues (like Soft 404s) common in migrations. I ensure your new Angular/Next.js setup is fully crawlable and returns correct HTTP status codes.
Why do you use AI tools like Cursor?
I use AI as an engineering assistant to scan for breaking changes in your legacy code faster. This allows me to deliver an enterprise-grade migration with higher accuracy and at a lower cost than traditional methods.
