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.
