Automated Web Scraping Pipelines & Data Extraction Services
Service Summary
I develop production-grade web scraping pipelines using Python, FastAPI, and n8n to extract structured product catalogs, competitor pricing, and research feeds. Designed to handle authenticated portals, dynamic Javascript DOMs, and anti-bot protections, my scrapers deliver clean data straight to Google Sheets, PostgreSQL, or your ERP on automated daily schedules.

Frequently Asked Questions
How do you bypass modern anti-bot protection like Cloudflare?
Standard HTTP libraries (requests, httpx) are blocked because Cloudflare inspects TLS handshake fingerprints (JA3/JA4). I implement curl_cffi which impersonates real browser TLS cipher suites and HTTP/2 frames, making requests indistinguishable from a standard Chrome browser.
Can the scraper run automatically without me touching anything?
Yes. By wrapping the scraper as a Dockerized FastAPI microservice and orchestrating it with an n8n cron workflow, the system runs completely unattended on your VPS or server (for instance, every morning at 4:00 AM).
Is web scraping legal and ethical?
Yes, when extracting public facts, product specs, or authorized wholesale supplier inventory for business operations while respecting server load and data-privacy laws. I follow responsible rate-limiting practices to avoid overwhelming target servers.
