Full Stack Developer Needed to Fix OpenAI Integration and Formatting Issue

I am looking for a full stack developer who can solve my website's current problem and update some of its functions. My project uses the OpenAI API. When a user uploads a PDF or document, the system automatically detects the text, sends it to OpenAI, and shows the reply on the dashboard in a formatted style. Right now the format of that reply is not correct and doesn't display the way it should. I just need someone who can check my current project, find what is causing the problem, and fix it so the response always shows properly on the dashboard. After that, I would also like to update a few existing functions, and I will share the details with the right person. The ideal developer has solid full stack experience and has worked with the OpenAI API before, especially on getting a clean, structured response from the AI and showing it correctly on the frontend. You should also know how to extract text from PDFs and documents, and be comfortable working with React, Node.js or Python. Since this is an existing project, you need to be good at reading and debugging someone else's code. Clear communication in English is important too, so you can explain what the problem was and what you changed. If you are interested, please tell me about a similar AI integration you have done, how you would approach this issue, and how long you think it will take and what it will cost. Please start your proposal with "AI Fix" so I know you read the full post.
