About this gig

A checkout total that does not add up, a form that will not submit, or an API returning the wrong data can interrupt your business and frustrate your users.


I investigate and fix reproducible bugs in existing React, Node.js, JavaScript and TypeScript web applications.


I can help with broken buttons and forms, login errors, cart and checkout logic, missing or incorrect data, and API integration issues.


Before making changes, I reproduce the problem and trace its cause. After the repair, I check the affected functionality and related behavior. You receive the updated code and clear notes explaining what changed and how it was verified. Premium workflow repairs include regression tests for the agreed issues.


Please message me before ordering with a description, steps to reproduce the issue, and screenshots or error logs. I will review the details and confirm the scope and package.

Packages cover agreed repairs in one existing application. New features, major rewrites, deployment work and additional issues require a separate quote. Revisions cover adjustments to the agreed repair.
