Acerca de este Servicio

Is your React, Nextjs, JavaScript, or TypeScript website not working the way it should?


I can help diagnose and fix bugs in existing websites and web applications. I work with modern frontend and full-stack technologies and can troubleshoot issues ranging from broken components to API, authentication, database, build, and deployment problems.


I can help with:


  • React and Nextjs bugs
  • JavaScript and TypeScript errors
  • Broken components or functionality
  • API and data-fetching issues
  • Forms and validation problems
  • Authentication and login issues
  • Responsive and mobile layout bugs
  • Build and deployment errors
  • Database-related problems
  • Performance and unexpected application behavior


I focus on finding the root cause of the issue and providing a clean, reliable fix without unnecessary changes to your project.


Please message me before ordering if your issue is complex or you are unsure which package is appropriate. Include the error, expected behavior, and any relevant screenshots or details so I can evaluate the problem first.
