Project Overview

Realty Pulse Pro is an AI-powered real estate intelligence and property operations platform built for brokers, agencies, and property consultants. The platform enables organizations to manage property listings, broker workflows, CRM pipelines, and intelligent customer engagement through customizable AI-powered property assistants. A major focus of the platform was building a Retrieval-Augmented Generation (RAG) based chatbot infrastructure where organizations could create dedicated projects, upload property datasets, configure AI assistants, and integrate those chatbots directly into their websites. The chatbot system allowed end users to ask natural-language real estate queries such as nearby properties, budget-based recommendations, location-specific searches, bedroom requirements, and contextual property discovery questions. The system leveraged OpenAI APIs, GPT-based conversational workflows, vector embeddings, semantic retrieval pipelines, FastAPI services, and FiasDB vector infrastructure to deliver contextual property recommendations and intelligent conversational search experiences. Uploaded property data was transformed into searchable embeddings enabling highly relevant retrieval workflows, AI-assisted property recommendations, and natural-language conversational responses. The platform also included CRM operations, realtime lead tracking, broker management systems, advanced property filtering, operational dashboards, and realtime customer interaction workflows. Redis-backed caching systems and optimized retrieval services improved response speed and platform scalability during concurrent user interactions. Dockerized deployment infrastructure and modular backend services enabled scalable operational environments while supporting multi-project chatbot deployments and realtime conversational workflows.
