Need AI/ML Engineer to Improve Existing AI Chatbot

I have an AI chatbot already built using LLM and RAG that needs some improvements before going live. The retrieval results aren't always accurate and the chatbot's responses need to be more consistent. Looking for someone with Python experience in RAG pipelines and LLM integration who can review the current setup, fix the retrieval/accuracy issues, and suggest any quick improvements to make it work better. This is a short, fixable-scope task please share examples of similar RAG/LLM work you've done before applying. Start your proposal with the word "AI/ML" to show you've read this job description.
