I will fix react nextjs and nodejs bugs errors and api issues
Hamza Nasar
About this gig
Is a bug blocking your React, Next.js, Node.js, or API project?
I will reproduce the issue, identify the root cause, and fix it cleanly in your existing web application.
I can help with:
- React component, state, hook, and responsive UI bugs
- Next.js routing, rendering, build, and deployment errors
- Node.js, Express, NestJS, REST API, and authentication issues
- Database, integration, environment, and Docker problems
- Small feature additions after the current bug is stable
You receive:
- A working fix in your existing codebase
- Clean, maintainable changes without unnecessary rewrites
- A short explanation of the cause and what changed
- Testing of the agreed issue before delivery
Please message me before ordering with the error, expected behavior, and repository or reproducible files. One package covers only the scope stated in its description. Paid services and unrelated issues are not included.

FAQ
What do you need to start?
Send the error, expected behavior, steps to reproduce, relevant code or repository access, and environment details.
What counts as a small bug?
One isolated issue in a single component, page, API route, or user flow. Please message me so I can confirm the scope.
Can you add a new feature too?
Yes. Choose Standard or Premium after we agree on the feature, dependencies, and acceptance criteria.
Do you work with JavaScript and TypeScript?
Yes. I work with JavaScript and TypeScript in React, Next.js, Node.js, Express, and NestJS projects.
Can you fix deployment or Docker errors?
Yes. I can investigate Vercel, Docker, build, environment, and deployment issues when logs and required access are available.
Can you work without full repository access?
Sometimes a minimal reproducible example is enough, but repository access usually makes diagnosis and testing more reliable.
Are third-party service costs included?
No. Hosting, API usage, paid plugins, domains, databases, and other third-party charges are paid by the buyer.
Will you explain what caused the issue?
Yes. Delivery includes a concise explanation of the root cause, the change made, and any important follow-up steps.
