I build scalable web scraping and data extraction systems for businesses that need reliable data from complex, JavaScript-heavy, and protected websites. With 3+ years of experience and 100+ custom scraping solutions delivered, I’ve developed production-grade pipelines that process millions of records monthly while maintaining high data accuracy and stability. My focus is on building long-term, maintainable scraping infrastructure, not fragile scripts that break after minor website updates.
