Freelancer Overview

I am a Python-based Web Data Extraction and Automation Specialist with strong experience scraping complex, JavaScript-heavy websites. I build scalable scraping workflows using Requests, BeautifulSoup, Selenium, and Playwright to extract structured data from dynamic, multi-level platforms. I focus on delivering clean, validated, and schema-compliant datasets in CSV and JSON formats. My expertise includes pagination handling, nested extraction, AJAX interception, data normalization, and error-handling mechanisms to ensure reliable automation. In addition, I have contributed to AI evaluation and fine-tuning workflows, ensuring structured, high-quality data delivery aligned with project requirements.
