About this gig

Have a small JavaScript or TypeScript bug?


Please message me before ordering with a minimal reproduction, the expected result, and your Node.js version. We will agree on one focused issue that fits this package.


You will receive:

- A targeted code fix for the agreed issue.

- A regression test and the command to run it.

- A short explanation of the cause and the change.


Good fits include CLI argument handling, data parsing, state synchronization, and timer cleanup in a small script or module.


This service uses AI-assisted development with focused tests. Please confirm that this workflow meets your project requirements before ordering. Larger features, full applications, and live production changes need a separate scope.


Share sanitized code and sample data. Do not send passwords, API keys, or private customer records. All order communication, delivery, and payment stay on Fiverr.
