AI Developer to Add an AI Automation Feature using Python, React, FastAPI, OpenAI, LLM & RAG

I need help implementing a focused AI automation feature that takes user input, processes it with an LLM, and returns structured results through a simple React interface. The task includes: - Connecting the OpenAI API to a small Python workflow. - Exposing the workflow through a FastAPI endpoint. - Adding a lightweight React UI to submit input and display results. - Using RAG to ground responses in a small set of reference documents, if needed. - Testing with sample inputs and handling common API errors. Skills needed: Python, FastAPI, React, OpenAI API, LLM integration, AI automation, and basic RAG concepts. The scope is intentionally small: one working feature, not a complete application or a large AI platform. When applying, briefly describe how you would implement this and share an example of similar work.
