Vasil Y
About this gig
Stuck with a React, Next.js, JavaScript, or TypeScript problem? I will reproduce the issue, identify the root cause, and deliver a focused fix without rewriting unrelated parts of your project.
Common issues I handle:
- Runtime, build, and TypeScript errors
- Broken components, forms, routing, and state
- API and authentication failures
- Responsive layout and browser compatibility bugs
- Performance regressions and rendering problems
- Dependency or configuration issues
You receive the corrected code plus a concise explanation of what failed and what changed. For accurate pricing, send the error, reproduction steps, repository details, and expected behavior before ordering.
