About this gig

Are you experiencing bugs in your Next JS, React, or TypeScript web application?

I will analyze the issue, find the cause, and provide a clean and carefully tested fix.

I can help with:

Next JS, React, and TypeScript bugs

Responsive design and mobile layout issues

Forms, validation, and user interface problems

API integration and data-loading errors

Authentication and account-related issues

Database logic with PostgreSQL and Prisma

Stripe payment integration issues

Performance problems and code cleanup

HTML and CSS styling fixes

How it works:

  1. Send me a description of the problem, screenshots, error messages, and access to the relevant source code.
  2. I will review the issue and confirm which package is suitable.
  3. I will implement and test the fix.
  4. I will explain what was changed.

Please contact me before ordering if the issue is complex or you are unsure which package to choose.

I work carefully, communicate clearly, and focus on practical fixes without unnecessary changes to your existing application.
