Web scraping, data scraping and data extraction from websites that block everyone else. I build Python scrapers and crawlers that survive where others fail — 1B+ structured records delivered over 12+ years. ✅ Top Rated Plus ✅ 100% Job Success ✅ 5.0 from 150+ reviews ✅ 160+ jobs ✅ $100K+ earned "We had an issue for the first time in the past many months of working with him and within 12 hours of us notifying him, it was fixed." — Upwork client Projects range from focused data extraction tasks to large-scale anti-bot resilient infrastructures — each engineered for stability, performance, and long-term reliability. My systems are built with Python, Scrapy, Playwright, and Selenium — combining web scraper development, browser automation, data mining, API integration, and ETL pipeline design. When data becomes mission-critical — reliability matters more than code. ────────────── What I Scrape ────────────── - Real estate — Zillow, Redfin, Realtor, Realtor Canada, Realestate Australia, PropertyGuru, 99co, Leboncoin + 100 more portals: listings, rentals, agents, agencies, price drops - E-commerce & prices — Amazon, eBay, Home Depot, Lowe's, Wayfair, Sephora, Back Market, Trendyol - Jobs & ATS — Greenhouse, Lever, Workday, Ashby, iCIMS, SmartRecruiters, Workable, Glassdoor - Tickets & travel — Ticketmaster, StubHub, Viagogo, Vivid Seats, Booking, Airbnb, Expedia, Skyscanner - Leads & reviews — Google Maps, Google Search, Yellow Pages, Yelp, Trustpilot, G2, LinkedIn, YouTube ────────────── What I Build ────────────── - Custom Python web scrapers and data extraction systems aligned with business logic - Scalable web crawlers — from selective datasets to millions of pages - Continuous update pipelines (batch & incremental ETL) - Queue-based distributed, high-concurrency processing - API-based data extraction and system integrations - Clean delivery to CSV / Excel / JSON / Google Sheets / PostgreSQL / MySQL / APIs / cloud storage - Automated validation, deduplication & anomaly detection You receive structured, business-ready datasets — not scripts to babysit. ────────────── Anti-Bot & Protection Layers ────────────── Modern platforms are protected. I work inside environments guarded by: - Cloudflare (403 / 429 / Turnstile) - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - TLS/JA3 fingerprint alignment & reverse engineering of detection vectors - Headless & browser fingerprint detection - hCaptcha / reCAPTCHA v3 Enterprise - Sustainable session & token lifecycle management This is not proxy swapping. This is controlled, sustainable access engineering. ────────────── Scale, Cost & Stability ────────────── At volume, scraping fails in two ways: stability collapses, or proxy and infrastructure costs explode. I tune concurrency, routing, batching and traffic patterns to keep throughput high and load controlled — reducing proxy and infrastructure costs by up to 30% where relevant. Websites evolve and protection layers update. I add structural drift monitoring and heartbeat checks that detect site changes before pipelines fail. Most developers fix scraping after it breaks — I design systems that minimize breakage from the start. ────────────── Who This Is For ────────────── - Founders building data-driven products - AI/ML teams requiring proprietary datasets - Businesses automating competitive intelligence, price monitoring or lead generation - Companies where reliable data access supports growth ────────────── How We Start ────────────── If needed, I provide a working sample first to demonstrate data quality and bypass stability. Payment is released only after you've checked the result. Send me: - Target website(s) - Required data fields - Expected volume - Update frequency - Preferred output format Whether it's a focused scraping task or a large-scale data infrastructure — let's build it properly.
