I will migrate angularjs to angular or upgrade your app to the latest angular
Sefat Anam
About this gig
Still running AngularJS, or several major versions behind on Angular? AngularJS reached end of life in December 2021, and every skipped version makes the next upgrade harder.
I'm a senior Angular developer with 6 years of production experience. I led the migration of JobDroid, an Australian job portal, from AngularJS to Angular 16 with server-side rendering, incrementally and without a feature freeze, and I work with every version from Angular 7 to Angular 21.
What I do:
- Audit your codebase and dependencies and write a clear, step-by-step plan
- AngularJS to Angular migration with ngUpgrade, so both run side by side
- Angular version upgrades, one major version at a time
- Fix breaking changes, RxJS and library updates along the way
- Move to standalone components and Signals where they pay off
- Add SSR (Angular Universal) when SEO or first load matters
How I work: small, reviewable commits, the app stays shippable after every step, and a clean handoff your team can continue from.

I write typed, maintainable code, ship in small reviewable updates and communicate clearly in English.

FAQ
Do we need a feature freeze during the migration?
No. I migrate incrementally, so AngularJS and Angular run side by side and your team can keep shipping features while the migration moves forward.
Which versions can you upgrade from and to?
Anything from AngularJS and Angular 7 up to the latest Angular. I upgrade one major version at a time and fix breaking changes at each step.
My app is large. Can you still help?
Yes. Start with the Audit and Plan package: you get a clear roadmap and estimate. Larger migrations are then split into milestones with a custom offer.
Will you add SSR or Signals while upgrading?
If it helps your app, yes. I have shipped Angular SSR in production and use Signals daily, and I only introduce them where they reduce risk or complexity.
