With 24,000+ hours and 143 completed projects on Upwork, I help data-driven companies build reliable, automated data pipelines โ€” from web scraping all the way to clean, structured data delivered into their dashboards, CRMs, and cloud platforms. Most clients come to me after dealing with fragile scrapers that break on every site update, or manual processes that eat 10+ hours per week. I fix both.
