About this gig
Is a bug stopping your web application from working correctly?
Im a Full-Stack Software Engineer with 3+ years of experience working with production applications using React, Next.js, TypeScript, Node.js, PostgreSQL and APIs.
I can help you diagnose and fix:
- React and Next.js bugs
- Frontend errors and broken UI behavior
- API and backend issues
- TypeScript and JavaScript errors
- Database-related problems
- Integration issues
- Forms and validation bugs
- Production errors
- Existing features that are not working as expected
I'm comfortable working with existing codebases, debugging unfamiliar projects and finding the root cause instead of applying temporary fixes.
Please contact me before ordering if the issue is complex or you are unsure which package fits your problem.
