About this gig

Hi!


Did you build an app with Lovable, Replit, Bolt.new, v0, Cursor, or another AI coding platform, but the code is buggy, messy, slow, or hard to scale?


I'm Usman, a senior full-stack developer with experience since 2016. I will audit, fix, and refactor your vibe-coded or AI-generated app to make it clean, stable, scalable, maintainable, and production-ready.


My services include:

  • Bug, build, and deployment fixes
  • AI-generated code cleanup and refactoring
  • React, Next.js, JavaScript, and TypeScript improvements
  • Component and architecture restructuring
  • Authentication, API, database, and integration fixes
  • Performance and responsive design improvements
  • Error handling, testing, and basic security
  • MVP and prototype production hardening


Why choose me?

  • Clean, industry-standard code
  • Clear communication and honest estimates
  • Responsive results for desktop, tablet, and mobile
  • Testing before delivery
  • Source code included


This Gig is for improving an existing app. Major features, migrations, or full rewrites may require a custom offer.


Please contact me before ordering so I can review your app and recommend the right package.


Regards,

Usman
