Expert Web Automation & Anti-Bot Engineer I specialize in building high-performance automation systems and data extraction pipelines for websites with the most advanced security layers. If you have been blocked by Cloudflare, DataDome, Akamai, or PerimeterX, I am the engineer who can help you scale. My core expertise lies in navigating the complex protection systems used by major marketplaces like Avito, Amazon, and eBay. I don't just write scripts; I build "Human-Mimicry" systems that remain undetected by sophisticated behavioral analysis. What I bring to your project: Advanced Browser Masking: I use patched versions of Playwright, Selenium, and Puppeteer (Stealth) to bypass headless detection, WebGL fingerprinting, and Canvas tracking. Infrastructure Mastery: Expert-level integration of Residential/Mobile proxy pools with sticky session management and custom TLS fingerprinting (JA3) to mimic real organic users. Sophisticated Logic: I implement Gaussian mouse movements, randomized scroll depths, and adaptive delays to neutralize behavioral sensors. CAPTCHA & JS Challenges: Automated handling of complex JavaScript challenges and cookie-based validation without manual intervention. Data Integrity: Efficient extraction of dynamic content, including AJAX-loaded data, hidden API endpoints, and obfuscated elements (like phone numbers or pricing). Scalability: My solutions are designed for high-thread environments, ensuring maximum speed without triggering rate limits. Tech Stack: Languages: Python (Scrapy, Selenium, Playwright), Node.js. Databases: PostgreSQL, MongoDB, Redis. Tools: Docker, Custom Proxy Managers, OCR for data decoding. I pride myself on building resilient systems. While others struggle with "Access Denied" screens, I focus on delivering stable, long-term access to the data you need. Let’s turn your data challenges into a competitive advantage.
