About this gig

Stuck on a bug in your React or Next.js app? I'll find the cause, fix it properly and explain what changed.


I fix things like:

- Errors, crashes and blank screens

- Hydration and SSR issues in Next.js

- Forms, state and data-fetching bugs

- Layout and responsive problems

- Build, TypeScript and dependency errors


You get a clean fix as a pull request or zip, a short written note on the cause, and a test where it makes sense.
