I build web scrapers that don't get blocked and don't break. 🛡️ If you've watched your bot get banned within minutes of hitting a site behind Cloudflare, DataDome, or Akamai — or inherited a brittle Selenium script that dies the moment the site changes — that's the problem I solve. I build data extraction systems designed to run for months, not days. 🔧 WHAT I BUILD High-volume scraping systems for: • E-commerce pricing & product data • Real estate listings • Business directories & lead generation • Contact extraction 🎯 THE HARD TARGETS This is where most scrapers fail and mine don't: • JavaScript-heavy SPAs, dynamic content, and infinite scroll • Login-gated pages • Serious anti-bot protection — Cloudflare, DataDome, Akamai, PerimeterX, CAPTCHA solving Where it's faster and more stable, I skip the headless browser entirely and reverse-engineer the site's internal API. For ongoing collection, I build scheduled crawlers with proxy rotation, session management, and browser fingerprint handling baked in. 💡 WHY CLIENTS HIRE ME Most scrapers on Upwork work once — on the developer's machine, on a good day. Mine ship with: • Retries, error handling, and failure alerts • Monitoring and scheduling, deployed on AWS or Docker — no babysitting • Clean, structured output: JSON, CSV, straight into PostgreSQL, or via a FastAPI endpoint — not a folder of messy HTML You'll also always know where the project stands. I communicate in plain English, flag risks early, and deliver fast. ⚙️ TECH STACK Python • JavaScript/TypeScript • Playwright • Selenium • Puppeteer • Scrapy • BeautifulSoup • FastAPI • Celery • Redis • Docker • AWS (EC2, Lambda, S3) • GitHub Actions Need the output AI-ready? I deliver structured data formatted for LLM and RAG ingestion. 📩 SEND ME A SITE Even one that's blocked every scraper you've thrown at it.
