Python Fast API Developer | AI Conversation History (FastAPI, OpenAI)

We’re enhancing our AI‑powered SaaS platform built with a React.js frontend and a Python FastAPI backend that integrates with the OpenAI API. While the assistant works well, it currently doesn't maintain conversational memory, which limits the user experience. We’re looking for a developer to implement a lightweight conversation history system that lets users revisit and continue past chats seamlessly.
