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. Send the URL and a sentence about what you need, and I'll tell you honestly whether it's feasible, how I'd approach it, and what it would take. keywords: python, scrapy, selenium, requests, beautifulsoup, lxml, web scraping, web crawling, automation, bots, scrapers, spiders, cloudflare, captcha, puppeteer, playwright, tutoring, real estate, e-commerce, lead gen, zillow, trulia, realtor, redfin, streeteasy, linkedin, airbnb, auction, tripadvisor, craigslist, sales navigator, ebay, amazon, google listings, pandas, discord, google maps, indeed, glassdoor, walmart, bestbuy, target, etsy, facebook, instagram, twitter, tiktok, builtwith, walmart, watch, captcha, incapsula, cloudflare, akamai, travel, yelp, yellowpages, booking, reviews, finance, crypto, reddit, hotel, motel, zyte, leads, cars, automotive, doctor, google search, API, rest API, pcpartpicker, truepeoplesearch, restaurants, insurance, g2, retailer, zapier, google sheets, fashion, behance, serp, excel, ec2, workspace, senior, expert, bot, spreadsheet, chatGPT, data mining,automobiles,overstock,wayfair,flipkart,rakuten,jd,aliexpress,newegg,homedepot,lowes,expedia,orbitz,hotwire,kayak,skyscanner,delta,americanairlines,doordash,apartments,rent,cars,autotrader,edmunds,tesla,ford,mercedesbenz,bmwusa,twitter,pinterest,quora,reddit,,crunchbase,angel,patreon,medium,soundcloud,crawler,shopify,product,membership,directory,clay,n8n,AI,supabase,apollo,airflow
