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.
