Debugging AI-Based Web Application

I have an existing AI-powered web application that currently has several bugs and technical issues that need to be fixed.

Tech stack:

* Frontend: React.js
* Backend: Python and Node.js
* AI/LLM integrations
* APIs and database

The project is already developed. I am NOT looking for someone to build a new application from scratch. I need an experienced full-stack developer who can review the existing code, identify the root causes of the bugs, and fix them properly.

Important: Due to the confidential nature of the project, I cannot share the full source code or upload the complete project to the freelancer.

The developer will need to work remotely on my laptop using remote-access software such as AnyDesk, TeamViewer, Chrome Remote Desktop, or another similar solution. The source code will remain on my computer.

I will explain and demonstrate the current bugs through screen sharing. You will then investigate the frontend, backend, APIs, and AI-related functionality, make the necessary changes directly on my laptop, and test the fixes.

I am looking for someone experienced with:

* React.js
* JavaScript / TypeScript
* Python
* Node.js
* REST APIs
* AI / LLM integrations
* Debugging existing applications
* Frontend/backend integration
* Database and API troubleshooting
* Git
* Working with large or unfamiliar codebases

AI project experience is strongly preferred.

The ideal developer should be a strong problem solver who can find the actual cause of a bug instead of applying temporary fixes. You should also be careful not to break existing functionality while making changes.

The initial task is to fix the current bugs and verify that everything works correctly. If the work goes well, there may be additional development and maintenance work afterward.

When applying, please provide:

* Your experience with React, Python, and Node.js
* Your experience with AI/LLM projects
* Examples of similar debugging work you have done
* Your hourly rate or estimated project cost
* Your availability
* The remote-access software you are comfortable using

Please apply only if you are comfortable working remotely on the client's computer. The full source code will not be transferred or shared outside my laptop.

I am looking for someone who can start as soon as possible.
