About this gig

Having a bug you just can't figure out? I can help you track down the cause and fix it.

I'm a web developer working with frontend and backend technologies. Whether your website has a broken feature, your API returns errors, or something suddenly stops working, I'll investigate the issue and work on a practical solution.

What I can fix:

  • JavaScript / TypeScript bugs
  • React UI and functionality issues
  • Backend errors (Node.js)
  • API and integration issues
  • Database-related bugs
  • Runtime and build errors
  • Responsive and browser-specific issues
  • Other web development problems

My tech stack:

  • Languages: JavaScript, TypeScript, Python
  • Frontend: React
  • Backend: NestJS, Flask
  • ORM: TypeORM
  • API documentation: Swagger

How I'll work:

  1. Investigate the issue and identify its cause.
  2. Implement a fix targeting the underlying problem.
  3. Test the affected functionality to verify the fix.

I value clear communication and aim to provide a solution that addresses your problem, not just its symptoms.

Please contact me before ordering. Describe your issue and share any relevant error messages or details about your project. I'll review your requirements and confirm whether I can help.
