I will fix bugs in your react or nextjs app
Devendra Kumar
About this gig
Something's broken, and you need it fixed today. I get it.
I debug React and Next.js apps, broken components, state issues, API errors, layout problems, hydration mismatches, you name it. Share your repo or paste the relevant code, and I'll find what's wrong and fix it.
What I check:
- Component and state logic
- API and data fetching issues
- Console errors and warnings
- Performance problems
- Auth and routing bugs
I don't just patch the symptom. I'll tell you what caused it, so it doesn't come back.
Basic covers one bug. Standard covers up to five with a written summary. Premium includes a full code review on top of the fixes.
Send me a message describing the issue before ordering. I'll confirm I can help within an hour.

I've been building things on the web for 9 years — and honestly, I still enjoy every part of it.
My work mostly lives in the Node.js + React + Next.js world. I've built REST APIs, wired them up to PostgreSQL, MongoDB, and Redis, and pushed them to production with CI/CD pipelines.
For mobile, I work with React Native, which means your iOS and Android apps share one codebase — and your budget goes further.
If your project involves Node.js, React, Next.js, React Native, or needs a solid backend API — I'm probably a good fit. Drop me a message, even if you're not sure what you need yet.
FAQ
How do I share my code with you?
A GitHub or GitLab repo link works best. If you do not use version control, you can send a ZIP file of the project. For smaller issues, pasting the relevant code in the chat is also fine.
What if you cannot fix the bug?
If I look at the issue and it is outside what I can fix, I will tell you before we proceed with the order. I would rather be upfront about it than take your money and deliver nothing useful.
How do you define one bug for the Basic package?
One clearly described problem with one root cause. For example, a button not working, a layout breaking on mobile, or an API call failing. If the issue turns out to have multiple causes, I will let you know and we can upgrade the order if needed.
Do you fix TypeScript errors?
Yes, both JavaScript and TypeScript. Type errors, missing types, and interface mismatches are all things I can sort out.
Can you fix issues in Next.js 13 or 14 with the App Router?
Yes. I work with both the Pages Router and App Router. Hydration errors, server component issues, and routing bugs in the newer Next.js versions are something I deal with regularly.
Will you explain what was wrong?
Yes. Every delivery includes a plain-English explanation of what the bug was and what I changed to fix it. You will not be left guessing.
What if my bug comes back after delivery?
If the same bug returns and my fix was the cause, I will fix it again at no charge. Revisions are included in every package for this reason.
