I will fix react js, next js and node js bugs and errors


About this gig
Is your React, Next.js, or Node.js app broken, throwing errors, or failing to deploy? I can help you find the root cause and get it working again.
I debug and fix existing React.js, Next.js, Node.js, and Express.js applications using JavaScript and TypeScript. I focus on targeted fixes - not full rewrites.
WHAT I CAN FIX
- React component, hooks, state, and rendering bugs
- Next.js routing, hydration, SSR, and build errors
- Node.js / Express API, backend, and server errors
- Broken forms, login, authentication, and API integrations
- Responsive UI issues, console errors, and deployment bugs
- MongoDB or PostgreSQL connection errors
WHAT YOU GET
- Root-cause investigation and a targeted code fix
- Basic testing of the affected functionality
- Clear explanation of what changed
SIMPLE PRICING
The $25 package covers ONE minor, reproducible bug. Need another minor fix or an automated regression test? Add a Gig Extra. Complex issues, major rewrites, new features, and unrelated bugs require a custom offer.
Please MESSAGE ME BEFORE ORDERING with the error, steps to reproduce it, and your tech stack so I can confirm the scope.

FAQ
What technologies can you debug?
I work with React.js, Next.js, Node.js, Express.js, JavaScript, and TypeScript. I can also investigate related API, authentication, UI, and database connection issues.
What is considered one bug?
One bug is a specific, reproducible problem with a defined expected result. Several symptoms caused by the same underlying issue may count as one bug. Please contact me if you are unsure.
Can you fix build errors or deployment issues?
Yes. I can investigate build failures, environment configuration, and deployment-related errors in supported projects. Complex hosting or infrastructure issues may require a custom offer.
Do you need access to my source code?
Usually, yes. You can provide temporary repository collaborator access or the relevant project files through the agreed Fiverr workflow. Please never send passwords, API keys, or secrets in plain text.
Can you fix bugs in an existing project developed by someone else?
Yes. I can review and troubleshoot existing codebases, provided the project is accessible and you have permission to share the code.
What happens if the bug is more complex than expected?
I will explain the findings and discuss the scope before proceeding with additional work. Larger tasks may need a custom offer and a revised timeline.
Are new features included?
No. This gig focuses on fixing existing functionality. New features, major redesigns, extensive refactoring, and security audits are quoted separately.
What do revisions include?
Revisions cover problems directly related to the agreed fix. They do not include unrelated bugs, new requirements, or additional features.
