About this gig

Your live application is broken. I take responsibility and fix it.


I resolve production incidents in deployed web applications crashes, failed deployments, login failures, and runtime errors affecting users or revenue.


This is not development work. This is production incident resolution.


What I handle

  • Build failures
  • Deployment errors
  • Authentication not working
  • Routes or pages crashing
  • Runtime errors in live apps
  • Revenue or user-blocking issues


Scope

I take ownership of one live production issue from diagnosis to resolution.

If its not actively breaking production, its out of scope.


What I need before starting

Please share:

  • The exact error message or screenshot
  • Where the error happens (build, deploy, or runtime)
  • Hosting platform (for example Vercel, AWS, etc.)


Important

This gig does not include:

  • New features
  • Refactors
  • Performance improvements
  • Idea-stage or local-only projects

I operate under the assumption that the issue is business-critical.

Respect third-party rights

Please be aware that it is against Fiverr's policies for sellers to include themes, templates, or any other elements that infringe third-party rights or applicable laws in the delivered work. Read more about in our Guide to Responsible Digital Creation.
