I will fix bugs and errors in your react, nextjs or angular app


About this gig
Stuck with a bug you can't figure out? I'll find the root cause in your React, Next.js or Angular app and fix it properly, not just patch the symptom.
I'm a senior software engineer with 5+ years of experience building production apps in both React and Angular. I'm a former contractor at Apple and currently a tech lead at a US SaaS company.
I can fix:
- Runtime errors, blank screens and console errors
- State issues: hooks, Redux, React Query, NgRx, signals
- RxJS problems: memory leaks, subscriptions, observables that don't emit
- Forms, validation and rendering/change detection bugs
- Build, deploy, TypeScript and dependency errors
- API integration and data-fetching problems
Any version: older Angular apps (v8+), React class components, and the latest Next.js App Router.
How it works:
- Message me before ordering with a description of the bug.
- Share repository access or the relevant code.
- I fix it, test it and deliver with a short explanation of what was wrong.

FAQ
Do you need access to my repository?
Read access or a zip of the code is enough. I deliver via pull request or patched files.
What if you can't fix it?
I'll tell you before starting, or refund if I can't deliver.
Do you work with old versions?
Yes, from Angular 8 and older React codebases up to the latest releases.
