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.

Hi, I’m Nazarii, a Full Stack Developer from Ukraine focused on fixing, deploying, and extending Next js apps.
I help founders and small teams with Next.js bugs, Vercel or Render deployment issues, Node.js errors, API integrations, Stripe billing, Supabase, OpenAI features, dashboards, and lean SaaS MVPs.
If you have an existing app, repo, or product idea, I can help debug the issue, connect the missing piece, or get the app live with clean code and clear communication.

FAQ
What do you need to start fixing the bug?
I need access to your source code, a clear description of the error, and steps to reproduce it. Screenshots or a short video are very helpful.
Can you start without repo access?
No. I need source code access through GitHub/GitLab or a full ZIP archive before I can begin debugging.
What counts as one bug?
One bug usually means one clear issue in a single flow, page, or deployment problem. If the fix touches multiple separate issues, I will review the scope before starting.
Can you fix bugs directly on a live website?
Yes, but it is safer to work on a local copy or staging environment first. Once tested, I will help you deploy the fix to the live site.
Does this include deployment problems?
Yes. Vercel build errors, failed deployments, missing environment variables, and production-only issues can be part of this gig when they are tied to one clear problem.
Do you work with databases and APIs?
Yes. I can debug backend logic, API routes, and database-related bugs when they are part of the reported issue.
Can you fix multiple bugs in one order?
Yes, but message me first. If the issues are separate, I will recommend a custom offer or a larger package so the scope is clear.
Do I get support after delivery?
Yes. I include a short post-delivery support window for the issue I fixed.
