AI Full Stack Developer for Real Estate AI Agent SaaS (LLM, Python, React)

We run a small real estate brokerage and want to build an AI agent that qualifies incoming buyer leads, matches them with listings from our database and hands warm leads to our agents in the CRM. We are looking for an AI Full Stack Developer who has already shipped an AI product or SaaS with LLM agents in production, ideally in real estate. What we need first: a paid discovery session of 1 to 2 hours. We walk you through our current process and data, you tell us what architecture you would choose, what an MVP should include and what it would roughly cost. If we are a good fit, we continue with the build. Stack we expect: Python (FastAPI), React, OpenAI or Claude API, a vector database for listing search. In your proposal please tell us: 1. One AI product you built that is closest to this, with a link if possible. 2. How you would match a buyer request written in plain text with listings. 3. Your hourly rate.
