I will fix bugs in your react, next js or node js application


About this gig
Is your React, Next.js or Node.js app broken and you need it fixed fast?
I am a Senior Full-Stack Engineer with 12+ years of experience. I have
built and maintained large-scale SaaS platforms in production I know
exactly where bugs hide and how to fix them without breaking anything else.
WHAT I CAN FIX:
- Broken UI components and layout issues
- API errors, failed requests and CORS problems
- Authentication and session bugs
- Database query errors and performance issues
- Build failures and deployment errors
- TypeScript and runtime errors
- State management issues (Redux, Zustand, Context)
HOW IT WORKS:
1. You share your code or repository access
2. I investigate the root cause
3. I deliver the fix with a clear explanation
4. You get working code no guessing, no back and forth
WHAT YOU GET:
- Bug fixed and tested
- Written explanation of what caused the issue
- Recommendations to prevent it from happening again
I treat every project with the same ownership I apply to my own products.
Message me before ordering if you are unsure which package fits your needs.
