I will migrate angular projects to angular 20, signals and standalone components
Usman Sultan
About this gig
Stuck on an outdated version of Angular? Dealing with deprecated packages and slow performance is frustrating when you just want to build features.
I specialize in untangling legacy code. I take outdated Angular apps (v9-v19) and safely migrate them to the latest Angular 20+.
Here is exactly how I help:
- Safe Upgrades: Step-by-step migration to the latest version without breaking existing features.
- Resolving Conflicts: Fixing npm dependency issues, RxJS deprecations, and build errors.
- True Modernization: I do not just bump the version. I refactor NgModules into clean Standalone Components and use Angular Signals for speed boosts.
- Tailwind Integration: Replacing clunky legacy stylesheets with clean Tailwind CSS.
- Performance: Removing dead code to slash bundle sizes and loading times.
Why work with me? I work daily with Angular, .NET Core, and C# on enterprise apps. I understand complex architecture, so you get clean, maintainable code your team will love working with.

FAQ
Do I need to provide access to my source code?
Yes, I will need access to your application's source code, typically through a secure repository like GitHub, GitLab, or Bitbucket. If you prefer, you can also share a ZIP file of the codebase (excluding node_modules). All your code remains 100% confidential.
Will my web application experience any downtime during the migration?
No, there will be zero downtime for your live users. I perform the entire migration and UI refactoring locally or in an isolated development branch. Once everything is thoroughly tested and approved by you, the updated version can be safely deployed to production.
Can you upgrade my app if it’s on a very old version like Angular 11 to 19?
Absolutely! I handle major version leaps by performing incremental, step-by-step upgrades. This disciplined approach ensures that database integrations, core logic, and complex dependencies don't break during the transition to the latest stable release.
What happens if my third-party packages or libraries are deprecated?
During the initial audit, I identify all outdated packages. I will either upgrade them to their latest compatible versions or replace them with modern, lightweight alternatives that offer the same functionality without bloating your application.
Can you completely change my old design to a new layout using Tailwind CSS?
Yes! If you select a package that includes UI modernization, I will completely strip out old Bootstrap or custom CSS and rewrite the frontend using utility-first Tailwind CSS. Your app will look ultra-modern and be 100% responsive across all mobile and desktop screens.
Do you write clean code, and will my future team be able to maintain it?
Yes, writing maintainable code is a priority. I refactor your application to align with modern best practices—such as using Standalone Components and Angular Signals—resulting in a clean, highly documented codebase that any developer can easily manage.
