Python web scraping specialist with a Master's degree in Computer Science and over 5 years of experience building reliable data extraction pipelines. I help businesses turn messy web data into clean, structured, usable information. What I do: • Scrape dynamic JavaScript-heavy websites (single-page apps, infinite scroll, lazy loading) • Extract data from Cloudflare-protected and other anti-scraping platforms • Parse complex PDF documents — including those with tables, formulas, images, and mixed Chinese-English content • Build automated monitoring pipelines for competitor pricing, product listings, and market research Recent project examples: - Extracted 15,000+ product reviews from a Cloudflare-protected eCommerce site, handling API pagination limits with dual-pass crawling - Built automated data extraction from directory websites (500+ records scraped and verified) - Processed PDF documents containing mathematical formulas and mixed-language content into structured Excel output I deliver: - Clean CSV/Excel files with proper headers and units - Well-documented, reusable scripts - Regular progress updates so you always know where things stand Fluent in both English and Chinese — I can handle projects that require either language. Let me know your requirements and I'll provide a quick feasibility check before we start.
