About this gig
Is your React app crashing, showing errors or not behaving the way it should? I'll find the cause and fix it properly, without quick hacks.
I'm a Senior React developer with 9+ years of experience on large production apps, including micro-frontends used by 10,000+ users.
What I can fix:
- Runtime errors, blank screens and build failures
- State bugs (Redux, Context, Zustand, React Query)
- Broken API calls, CORS and authentication issues
- TypeScript errors and failed dependency upgrades
- Slow renders and performance problems
- Responsive and CSS layout issues
How it works:
1. Send me the issue and access to the repo
2. I reproduce it, fix it and explain what was wrong
3. You get the clean code as a commit or pull request
Please message me before ordering so I can confirm the scope. Usually I can reply within a few hours.

FAQ
Which React versions do you work with?
All modern versions (16 to 19), including Next.js with both the Pages Router and the App Router.
Do you need access to my repo?
Yes. GitHub or GitLab access works best, or you can send the project as a zip. I'm happy to sign an NDA if you need one.
What if the bug turns out to be bigger than expected?
I'll tell you before doing any extra work and send you a custom offer, so there are no surprises.
