Informazioni su questo servizio

Broken UI, API error, failed build, or Vercel issue in your Next.js app?

I debug real problems in Next.js, React, Node.js, Tailwind CSS, and Vercel apps. I focus on finding the root cause, fixing the issue cleanly, and explaining what was wrong in plain language so you are not left with another mystery error.

What I can help with:

  • UI, CSS, and responsive issues
  • React state and component logic bugs
  • API and backend errors
  • forms, routing, and App Router issues
  • hydration and rendering problems
  • database-related bugs
  • Vercel build, deploy, and production errors

This gig is best for one clear issue per order. Basic is for a small UI or styling fix. Standard is for one logic, form, API, or routing issue. Premium is for deeper debugging such as hydration, backend, database, or production deployment problems.

Please message me before ordering with the error, expected result, steps to reproduce it, and any screenshots or logs. Source code access through GitHub, GitLab, or a full ZIP archive is required before I start.

    I am very satisfied working with Nazarii. As always, he delivered the tasks quickly, professionally, and with great attention to detail. What I appreciate most is that he really understands the system and thinks about stability, architecture, and long-term quality instead of just rushing through tasks....
