I will fix bugs or add features to your react nextjs or nodejs app
Gagan Chaudhary
About this gig
Stuck on a bug that has eaten your whole afternoon? I will find it, fix it, and explain what went wrong.
I work on React, Next.js, and Node.js / Express applications. Common issues I resolve:
- UI bugs (layout breaks, responsive issues, hydration errors)
- API errors (CORS, 404/500 responses, broken fetch logic)
- Authentication bugs (JWT issues, session handling, redirect loops)
- State management problems (Redux, Zustand, React Context)
- Performance issues (slow renders, unnecessary re-renders, large bundle)
- TypeScript type errors and build failures
I have 3+ years of production development experience, including enterprise systems at ICICI Bank where code quality and reliability were non-negotiable. I treat your codebase with the same care I would my own.
Before ordering, message me with a brief description of the issue. I will confirm whether it falls within the package scope and give you an honest estimate.

I build custom websites, web apps, and e-commerce stores for businesses — end-to-end, from brief to deployment. 3+ years building production systems at ICICI Bank means your project gets financial-grade reliability, not just a pretty site.
What I deliver: React / Next.js web apps, WordPress & Shopify stores, responsive landing pages, and API integrations. Clean code, on-time delivery, and clear communication throughout.
Clients in the UK, US, and India trust me to take full ownership — and deliver.

FAQ
How do I share my code with you?
The cleanest option is a private GitHub or GitLab repo — I will submit fixes as a pull request for you to review. If you do not use Git, a zip of the relevant files works fine. I do not need your full codebase, just the relevant folder or files.
What if you are unable to fix the bug?
If I take on your order and cannot resolve the issue within the agreed timeframe, I will issue a full refund. I am always upfront in the pre-order message if a problem looks out of scope — I would rather decline than deliver something that fails.
What frameworks and libraries do you support?
My primary stack is React (Create React App, Vite, Next.js), Node.js with Express, and TypeScript. I also work with Tailwind CSS, Prisma, PostgreSQL, and REST APIs. Message me if your stack differs and I will let you know if I can help.
