Python Web Scraping & Data Intelligence Platform

Production Python scraping system for leads, prices, and listings. Uses Scrapy and Playwright for JS-heavy sites, rotating proxies, rate-limit handling, and clean CSV/JSON/MongoDB export. Built as a FastAPI dashboard so clients can launch spiders, watch jobs live, and download structured data. Built with clean modular architecture, rigorous automated testing, and comprehensive logging. Designed from the ground up for high reliability, security, and lightning-fast user interactions.
