React, JavaScript and TypeScript Bug Fixing

Is your frontend application displaying errors, behaving unexpectedly, or failing to work as intended?

I can help investigate, diagnose and fix frontend issues in existing React, JavaScript and TypeScript projects.

What I can help with

  • React component errors and rendering issues
  • JavaScript and TypeScript bugs
  • API integration and frontend data-display problems
  • State management and interaction issues
  • Responsive layout and CSS problems
  • Browser console errors
  • Form validation and UI behaviour
  • Small frontend improvements and code cleanup

My approach

  1. Review the problem and relevant project files.
  2. Identify the likely cause before changing code.
  3. Implement a focused, maintainable correction.
  4. Test the affected functionality.
  5. Explain what was changed and provide the updated files or agreed code delivery.

What you'll receive

  • A focused solution for the agreed issue
  • Clean and maintainable code
  • Testing of the affected functionality
  • Clear communication about findings and limitations

Have a more complex issue? Contact me before ordering so we can confirm the scope, repository access requirements, estimated effort and delivery time.
