About this gig

️ SPECIAL OFFER: I am new to Fiverr and building my reputation here. I'm offering expert-level debugging at a discounted rate for my first 3 clients. You get senior-level troubleshooting for the price of a basic fix!

I am a frontend developer specializing in React.js, Next.js, and TypeScript. I don't just "patch" bugs; I find the root cause in your code logic to ensure the issue never comes back.

What I can fix for you:

  • React & Next.js Issues: Hook errors (useEffect/useState), Props drilling, and State management bugs (Zustand/Redux).
  • Next.js Specifics: Hydration errors, SSR/SSG build failures, and routing issues.
  • API & Data: Broken fetch/axios requests and asynchronous logic errors.
  • Advanced CSS: Complex responsive layout breaks, Tailwind CSS issues, and z-index/positioning nightmares.
  • Performance: Finding memory leaks and optimizing slow components.

Why choose me?

  • Senior-level logic: Clean, maintainable, and well-commented code.
  • Consultation-first: I analyze your repository before we start to ensure a 100% success rate.
  • Fast delivery: Most bugs are identified and fixed within 24 hours.

️ IMPORTANT: Please message me with a description of the bug and a link to your website/repos
