About this gig
Is your React or Next.js app stuck on a reproducible bug, failed build or broken API flow? I will investigate the agreed issue, make a focused fix and verify the affected behavior. AI-assisted codebases are welcome.
I am Narasimha, founder of Neufology. I work across React, Next.js, Node.js, APIs and database-backed SaaS products.
BASIC: one clearly defined bug in one application.
STANDARD: up to three related bugs with regression checks.
PREMIUM: up to five related bugs, targeted tests where practical and build verification.
Typical issues include runtime errors, state handling, API responses, forms, routing and deployment build failures. You receive the patch or source changes, a test summary and handover notes.
New features, redesigns, full rewrites, malware cleanup, guaranteed performance scores and open-ended maintenance are excluded. If the cause requires a larger architectural change, I explain the options before expanding scope. Send reproduction steps, errors and your stack on Fiverr before ordering. Keep secrets and customer data out of screenshots.

FAQ
Can you work on an AI-generated codebase?
Yes, if you own or are authorized to modify it and can share the source and a reproducible issue. I inspect the actual behavior and dependencies before promising a fix. A full rewrite or undocumented new feature is outside these packages.
What counts as one bug?
One agreed, reproducible failure with a defined expected result in one app. Several symptoms from one cause may be one issue; unrelated features are separate. We confirm the list and acceptance checks before work starts.
Do you guarantee every problem or score will be fixed?
No. Packages cover the agreed bug list, not every issue, performance score or third-party outage. One Basic revision or two Standard/Premium revisions correct the agreed fixes. Larger architectural work requires a separate scope.
