PropMetrics
Real estate intelligence platform for the Argentine market
Role: Creator & Developer
Rol: Creador y Desarrollador
Overview
A real estate data platform that automates property data collection from major Argentine portals (ZonaProp, Argenprop) and provides market analysis tools. Features advanced search, price history tracking, market statistics, and a buy vs. rent ROI calculator — built to bring data-driven decision making to Argentina's real estate market.
The Challenge
Argentina's real estate market lacks transparent, centralized data. Property listings are scattered across multiple portals with no easy way to track price changes, compare neighborhoods, or analyze market trends over time.
The Approach
Built a Spring Boot backend with Jsoup and Selenium for scraping, PostgreSQL for persistence, and Redis for caching. Implemented anti-bot measures like User-Agent rotation, random delays, and headless browser strategies. The API exposes advanced search, statistics, and financial analysis endpoints.
The Outcome
Backend API fully functional with data from two major portals covering Buenos Aires. Roadmap includes ML-powered valuations, heatmaps, and a React/Next.js frontend.
