I will fix bugs in your nodejs and expressjs backend


About this gig
Having issues with your Node.js or Express.js backend? I can help investigate and fix bugs in your existing application.
I work with Node.js, TypeScript, Express.js, MongoDB, and PostgreSQL to troubleshoot backend issues and implement focused, maintainable fixes.
What I can help with:
Fixing broken API endpoints and unexpected responses
Debugging Express.js routes and middleware
Troubleshooting authentication and JWT issues
Fixing MongoDB or PostgreSQL integration problems
Resolving request validation and error-handling bugs
Investigating incorrect status codes and backend logic
My process:
1. Review your issue and relevant code.
2. Identify the likely root cause.
3. Implement a focused fix.
4. Verify the affected behaviour and summarize the changes.
Before ordering, please share the error message, expected behaviour, actual behaviour, and relevant code or logs.
Packages cover only the stated scope. New features, major refactoring, deployment, and unrelated bugs are not included unless agreed separately.
I will treat your code and project information confidentially.

FAQ
Can you add new features or deploy my application?
New features, major refactoring, and deployment are outside the standard bug-fixing package. Send me the requirements first, and I can confirm whether the work fits the scope or needs a separate offer.
What do you need from me to start?
Please provide the relevant source code or repository access, steps to reproduce the issue, the expected and actual behavior, and any relevant error messages or logs. Never send production passwords, private keys, or live database credentials.
Do you work with MongoDB and PostgreSQL?
Yes. I can investigate issues involving MongoDB or PostgreSQL integration in Node.js applications. Please share the relevant schema or model, query, error message, and expected result.
Can you fix any Node.js backend bug?
I can help with many Node.js and Express.js issues, including API errors, middleware problems, authentication bugs, and database integration. Please message me with the issue first so I can confirm it fits the package scope.
