I will fix react bugs and improve your front end
Ernesto T.
About this gig
Is a React or JavaScript bug blocking your release or frustrating your users? I will investigate the problem, identify the root cause, and deliver a clean, tested fix.
I have 6 years of experience building and maintaining web applications across education, media, travel, and commerce. I work with React, JavaScript, REST and GraphQL APIs, accessibility, performance, testing, and production support.
I can help with:
React component and state issues
JavaScript errors and unexpected behavior
UI and responsive layout bugs
API integration problems
Accessibility defects
Performance issues
Refactoring related to the agreed bug
Before ordering, please message me with the issue, steps to reproduce, and relevant project details so I can confirm the right package. I will keep communication clear and explain what changed.

FAQ
Can you work with a private repository?
Yes. Please share access securely through Fiverr after the order starts. I will only use it for the agreed work.
Do you work with REST and GraphQL APIs?
Yes. I can diagnose front-end integration issues involving REST or GraphQL endpoints, authentication flows, response handling, and error states.
What counts as a small bug?
A small bug has clear reproduction steps and a focused cause, such as a component error, UI behavior issue, or isolated integration problem. Contact me first if the scope is uncertain.
