I extract large-scale structured data from websites that are hard to scrape, and enrich it with AI-powered analysis before it reaches your database. My clients are typically investment firms, proptech companies, and data providers who need production-grade data pipelines that run reliably without babysitting. Recent example: I built and maintain a system that extracts 1M+ property records weekly from Zillow, Realtor, Redfin, and InvestorLift for investment firms, with 99.9%+ accuracy and automated daily updates. AI-powered data enrichment: I integrate OpenAI and LLM APIs into extraction pipelines to score listings, analyze text confidence, classify unstructured content, and flag anomalies. Full record discovery: I reverse-engineer search APIs, pagination logic, and hidden endpoints to find every record, even when sites don't offer bulk access. Self-healing infrastructure: My systems detect rate limits, rotate sessions, and recover automatically. Clients get data on schedule. End-to-end delivery: Extraction, validation, deduplication, AI enrichment, and delivery via API, database, or scheduled exports. I also build monitoring dashboards and GUI applications for non-technical teams. Domains: real estate (MLS, permits, inspections, listings, rentals), e-commerce (price monitoring, inventory), job markets, and government/municipal portals. Tech: Python, Scrapy, Playwright, Selenium, OpenAI API, Django, Flask, Docker, AWS/GCP, CI/CD. Available for one-time extractions and long-term maintained systems with full documentation and deployment support.
