I will fix react, next js and node js bugs, api errors and build issues


About this gig
React page crashing, Next.js build failing, or Node.js API returning errors? I will diagnose the root cause and fix the agreed issue in your existing web app.
I debug React, Next.js, Node.js, Express and TypeScript applications, with experience working on production LMS platforms.
ISSUES I FIX
- React bugs: infinite re-renders, state updates and broken components
- Next.js errors: hydration, SSR, routing and failed builds
- Node.js bugs: API errors, middleware and async failures
- Authentication: login, JWT and OAuth issues
- TypeScript: type errors and compilation failures
- Integrations: REST APIs, Firebase, MongoDB and PostgreSQL
WHAT YOU RECEIVE
- Root-cause diagnosis and a focused code fix
- Testing of the affected feature and related flows
- Updated source code with a clear explanation of the changes
Packages cover agreed bugs in an existing codebase. New features, redesigns and extensive refactoring require a separate quote. Revisions cover the original issue.
Before ordering, send the error message, steps to reproduce and relevant code through Fiverr so I can confirm scope, price and delivery.

FAQ
What do you need to start?
The error message, steps to reproduce, expected behavior, relevant source code or repository access, and setup instructions.
What counts as one bug?
One reproducible issue with an agreed expected outcome. Separate failures or additional affected features may require a different package or custom offer.
Can you fix production or deployment errors?
Yes, after reviewing the logs, environment and access requirements. Any deployment work must be included in the agreed scope.
What do revisions cover?
Revisions address the original agreed issue. New features, unrelated bugs and changes to requirements are quoted separately.
Do you work with private repositories?
Yes. Provide access to the relevant repository and setup instructions. Remove unnecessary secrets and use limited-access test credentials where possible.
