About this gig

Your React or Next.js app throws errors, the build fails on deploy, or an API call breaks for no clear reason? I'll find the root cause and fix it properly.


I'm a full-stack developer working on an enterprise ERP system built with JavaScript, Node.js and React. I fix bugs in real codebases without rewriting what already works.


What I fix:

- React and Next.js runtime errors and hydration issues

- Build and TypeScript errors (locally or on Vercel)

- Broken forms, state and rendering bugs

- Node.js / Express and ASP.NET Core API errors

- Failed requests between frontend and backend

- PostgreSQL query and data issues


What you get:

- A clean fix in your GitHub repo as a separate branch or pull request

- A short report: root cause, what changed, how it was tested

- No unrelated changes to your code


Please message me before ordering with a description of the bug and, if possible, the error message or a screenshot. I'll confirm the scope and the right package.
