I will fix one issue in your vibe coded react or next js app
Marko C.
Über diesen Service
If your AI-built React/Next.js app is mostly working but one specific issue is blocking you, I can diagnose and fix it without turning it into an open-ended development project.
This Gig is for one defined, reproducible problem in an existing React/Next.js codebase, including projects started with tools such as Cursor, Claude Code, Lovable, Bolt, Replit, or v0.
Good fits include:
a broken component or interaction
a responsive or layout issue
incorrect rendering or state behavior
a TypeScript/JavaScript frontend error
a form/button/routing issue
a frontend data-display problem where the existing API works.
I will reproduce the agreed issue, make the necessary code change, run relevant verification, and provide a short written handoff explaining what changed.
This Gig does not include new backend development, authentication/payment systems, database work, new API integrations, security testing, deployment/hosting troubleshooting, broad refactoring, multiple unrelated bugs, or production access.
Please send one specific issue with reproduction steps and expected behavior. If the problem depends on an external system or falls outside this scope, message me before ordering.

I help founders and small businesses test, fix, and extend React and Next.js websites and web apps. Current work focuses on pre-launch QA, clearly defined repairs, and small REST API integrations, including AI-built or vibe-coded projects. I’m a solo operator. My workflow is human-led and AI-assisted: scope is agreed in writing, work is personally reviewed, and delivery includes a clear handoff. I prefer async, defined work over open-ended development, production firefighting, or emergency support.

FAQ
Can you work on apps created with Lovable, Bolt, Cursor, Replit, v0, or Claude Code?
Yes, when the underlying project is an accessible React or Next.js codebase and the issue fits this Gig's scope. The AI tool itself is not the deliverable; I work on the resulting code.
What counts as one issue?
One issue is one reproducible user-visible or developer-visible problem with one agreed expected outcome. Several symptoms may belong to the same issue if they have the same underlying cause. Multiple unrelated problems require separate scope.
Do you need access to my production environment?
No. I prefer to reproduce and fix the problem from the source code and a local or safe development setup. Do not send production credentials unless a separately agreed scope genuinely requires them.
Do you fix backend, database, authentication, payments, or deployment problems?
Not under this package. This Gig is intentionally focused on a defined React or Next.js issue. If the frontend problem depends on one of those systems, message me before ordering so I can determine whether the issue fits.
What will I receive?
The agreed code fix, relevant verification of the affected behavior, and a short written handoff explaining what changed and what was checked.
What if the problem turns out to be larger than described?
I will not silently expand the order. If investigation shows that the issue depends on a broader system or additional unrelated work, I will explain the finding and we can agree on the appropriate next step.
