Über mich
Python Developer & Data Extraction Specialist
I am a Python Developer specializing in high-performance Web Scraping, ETL pipelines, and Competitor Intelligence systems.
What sets my service apart is a solid foundation in Cyber Security. I don’t just write basic scripts that get banned after a few hundred requests. I design resilient, stealth data extraction architectures capable of bypassing modern anti-bot protections (Cloudflare, Akamai, advanced WAFs) using premium proxy rotation, TLS fingerprint mimicking, and human-behavior emulation.
