About this gig

Is your web application showing errors, broken features, or unexpected behavior? I will troubleshoot and fix bugs in your existing web application so it works as expected.

I can help with:

Next.js and React errors

JavaScript and TypeScript bugs

API and backend issues

Authentication and authorization problems

Supabase, PostgreSQL and MongoDB issues

Forms, validation and state management

Third-party API integrations

UI functionality and responsive issues

Vercel, Netlify and deployment errors

Runtime and production errors

Performance-related issues

I will investigate the problem, identify the root cause, implement the appropriate fix, and test the affected functionality.

Whether you have a small frontend bug, a database error, an authentication problem, a broken API, or a more complex issue involving multiple parts of your application, I can help.

Please contact me before ordering for complex issues. Send the error message, screenshots, relevant code, repository, or steps to reproduce the problem so I can understand the scope and recommend the right package.

Multiple unrelated or complex issues may require a custom offer.
