About this gig

Is a React component failing, a button doing nothing, or a JavaScript error breaking your web app?


I will investigate and fix a clearly scoped issue in your existing React project using JavaScript or TypeScript. Examples include component logic, state updates, event handlers and frontend handling of existing API responses.


You receive the source changes, a short explanation of the cause and verification of the agreed user flow. I will also run relevant existing checks where available.


Basic covers one small, reproducible bug. Larger issues need a scope review. A full rebuild, new features, backend development and production deployment are excluded.


Please message me with reproduction steps, expected behavior, error messages and your project setup before ordering so I can confirm the package and timeline.
