I will fix bugs in your javascript nodejs or nextjs web app


About this gig
Is your JavaScript, Nodejs, or Nextjs app showing an error, failing a request, or behaving differently from the expected result?
I will diagnose and fix a clearly reproducible bug in an existing codebase. Suitable tasks include runtime errors, broken API calls, form or validation issues, route failures, build errors, and small frontend or backend logic defects.
What is included:
Review of the relevant code and error details
A fix within the selected package scope
A brief summary of the cause and changes
Basic verification of the repaired flow
Please message me before ordering with the symptoms, steps to reproduce, repository size, and tech stack. Access must be provided through Fiverr approved methods.
This gig covers bug fixes only. New features, redesigns, migrations, large refactors, urgent production incidents, paid third party services, and unrelated issues require a custom offer. A revision means an adjustment to the agreed fix, not a new issue or feature.
If the problem depends on unavailable credentials, a third party outage, or cannot be reproduced, we will agree on the safest next step through Fiverr.
