I will fix bugs or add features to your react application


About this gig
Is your React or Next.js app full of bugs, unfinished features, or AI-generated code that works... but not quite the way it should?
I'm a Software Engineer with 8+ years of experience building and maintaining web applications. I can help fix, improve, and extend your existing app without rebuilding everything from scratch.
What I can help with:
- Fix React / Next.js bugs and unexpected behavior
- Add new features to your existing app
- Refactor and clean up problematic code
- Turn AI-generated code into production-ready software
- Improve performance and fix inefficient code
- Integrate APIs, third-party services, and AI features
- Handle full-stack tasks when a frontend-only solution isn't enough
Why work with me?
I focus on understanding your existing codebase and delivering reliable, maintainable solutions without unnecessary changes.
I don't limit the work to the frontend. If your issue requires changes to the backend, API, database, authentication, or architecture, I can handle the complete solution.
Have a specific problem? Message me before ordering and I'll review what needs to be done.

FAQ
Can you review my project before I place an order?
Yes. Feel free to contact me before placing an order. I can review your requirements and, when needed, look at the relevant parts of your codebase to understand the issue, determine the scope, and provide a clear price before we start. The initial discussion and assessment are free.
Can we have a call to discuss the project?
Absolutely. For complex or unclear requirements, we can arrange a quick Google Meet call so you can explain the issue, show me what you need, and discuss the expected result.
Can you fix AI-generated code?
Yes. I can fix and refactor code generated by Cursor, Claude, ChatGPT, Lovable, Bolt, v0, and similar AI tools, helping turn AI-generated MVPs into reliable, production-ready software.
Do you only work on the frontend?
No. If solving the problem requires changes to the backend, APIs, database, authentication, or other parts of the application, I can handle them as part of the solution.
What do you need from me to get started?
Usually, I need a description of the issue or feature, access to the relevant code or repository, and any information needed to reproduce the issue or understand the expected result.
