About this gig

Is a Node.js error, JavaScript exception, or TypeScript issue breaking your web app?


I will investigate and fix an agreed bug in your existing JavaScript or TypeScript application, with a tested patch and clear explanation.


I can help with Node.js and NestJS backend errors, REST API failures, async logic, validation, MongoDB or SQL issues, and JavaScript or TypeScript build errors.


How it works:

1. Send the error, reproduction steps, expected behavior, and relevant code.

2. We agree scope and package before ordering.

3. I reproduce the issue, apply the fix, and check the affected flow.

4. You receive the changes, test notes, and a brief handover.


Packages cover 1, 2, or 3 agreed bugs in one application. New features, full rewrites, hosting costs, and unrelated issues are outside scope. Please message me before ordering so I can confirm feasibility.
