Sobre este Serviço

Is your website broken, slow, or full of bugs affecting your users and conversions?

Even small bugs can break functionality, reduce performance, and hurt your business.

I help you fix issues quickly and improve your application stability.

I will fix bugs in your Next.js, React, or JavaScript website using AI-assisted debugging and performance optimization techniques.


What you will get

  • Fix JavaScript / React / Next.js bugs
  • AI-assisted debugging (faster issue detection)
  • Performance optimization
  • Error fixing (console, API, UI issues)
  • Clean and maintainable code
  • Responsive fixes
  • Debugging complex issues


Why this works:

  • Faster debugging = less downtime
  • Clean code = fewer future bugs
  • Optimized performance = better user experience


Most developers fix symptoms.

I fix root causes.

    There was a glitch with the design on the expiration box on the last page of the design. Seller told me it was a cache stored in phones browser. I trusted him and gave him the benefit of doubt but after delivery I discovered it was an error in the code. When I tried to contact seller, he made himself unavailable to contact and disappeared.
