React migrationdeveloper

I move legacy and dated frontends to React and Next.js incrementally - jQuery, CRA, Pages Router, or Angular - so you keep shipping and never bet the company on a big-bang rewrite. Remote, $25–57/hr.

React and Next.js migration: incremental, strangler-fig migrations from jQuery, CRA, Pages Router, or Angular to a modern typed React/Next.js codebase. Remote, $25–57/hr.

What you get

Incremental, not big-bang

A strangler-fig approach: migrate page by page or feature by feature while the old app keeps running.

ReusableComposableTypedTested

Keep shipping

Your team keeps delivering features during the migration - no months-long freeze, no rewrite gamble.

Typed & modern

Land on a clean React/Next.js + TypeScript foundation with the App Router and modern patterns.

Low-risk path

A clear, reversible migration plan with checkpoints, so risk stays contained at every step.

How I migrate without a rewrite

I map the current app, pick the safest seams, and migrate incrementally - wrapping or replacing one route or feature at a time. The legacy app and the new React code run side by side until the move is complete.

You get a written migration plan with checkpoints, so you can see progress and stop or adjust at any point.

  • CRA / Vite β†’ Next.js
  • Pages Router β†’ App Router
  • Angular / other β†’ React (incremental)

What you end up with

A modern, typed React/Next.js codebase your team can build on - faster, more maintainable, and ready for the next few years instead of fighting the last few.

Good fit

Who this is for

  • Teams on jQuery, CRA, or old Angular
  • Apps stuck on the Pages Router wanting the App Router
  • Products that cannot afford a feature freeze
  • Anyone burned by a failed big-bang rewrite
Probably not

Not the right fit if…

  • You want a from-scratch rewrite with no legacy constraints
  • There is no migration target in React/Next.js
FAQ

Frequently asked questions

Still unsure? Email me - I reply within 24–48 hours.

01Do I have to rewrite everything at once?

No - that is the whole point. I migrate incrementally (strangler-fig), so the legacy app keeps running while React/Next.js takes over piece by piece.

02What migrations do you handle?

jQuery/vanilla β†’ React, CRA/Vite β†’ Next.js, Pages Router β†’ App Router, and Angular/other frameworks β†’ React, all done incrementally with TypeScript.

03Can my team keep shipping during the migration?

Yes. The incremental approach is designed so feature delivery continues - no long freeze and no all-or-nothing cutover.

04What are your rates and availability?

$25–57/hr depending on scope, UK-based and remote, replies within 24–48 hours.
