What you get with this Offer
Your backend is failing and your entire product is on hold because of it. Every failed API call is a broken user experience, and every hour you spend debugging alone is an hour your product is not moving forward. That ends here.
I am a Full Stack MERN Developer with 15 months of professional experience building and fixing production backends using Node.js, NestJS, Express and MongoDB. I have worked on real client projects where a broken API meant real business impact, so I understand the urgency and I treat every fix that way.
Here is what I fix:
Broken or unresponsive REST API endpoints
Incorrect HTTP status codes and response structures
Authentication failures in JWT and OAuth flows
Database connection drops and Mongoose query errors
Middleware conflicts in Express and NestJS
CORS misconfigurations blocking your frontend
Environment variable and configuration issues causing silent failures
Rate limiting or timeout problems under load
What makes my approach different is that I do not just patch the surface. I trace the issue to its actual root, fix it cleanly, test it before I hand it back, and explain what went wrong so you are not stuck with the same problem two weeks later.
Here is what you will receive:
A fully working fix with clean tested code
A short explanation of what went wrong and why
Free re-fix if the same issue returns within three days
Share your repo, error logs, or even just describe what is happening and I will take it from there.

What the Freelancer needs to start the work
1. Describe what your API is supposed to do and what it is doing instead.
2. Share the error message or logs you are seeing on your end.
3. Provide access to your code through a GitHub repository link or a zip file of the relevant files.
4. Let me know your tech stack including your Node version, whether you are using Express or NestJS, and your database setup.
5. Share any screenshots or screen recordings if the issue is visible on the frontend side as well.
The more context you give me upfront, the faster I can diagnose and fix the issue without unnecessary back and forth.
