Hire the Best Web Crawler Developers

Most scrapers pull from public pages. I get data out of systems you have to log into... carrier portals, practice management tools, supplier back offices, vendor dashboards with 𝐧𝐨 𝐀𝐏𝐈 and no export button. Previous results: - Recovered over $𝟑𝟎𝟎,𝟎𝟎𝟎/𝐲𝐫 for eight insurance agencies by automating their carrier portal forms - Generated $𝟐𝟓,𝟎𝟎𝟎 of new opportunities in just one month for a B2B data-analytics firm by scraping fresh leads from behind a login - Saved $𝟐𝟖,𝟎𝟎𝟎/𝐲𝐫 of support capacity for a CRM software company by integrating AI with their helpdesk I've shipped 30+ production systems and these are systems that non-technical people depend on every day. ✅ Before You Hire Me Send me the target and I will run a working sample first, at my cost, so you can see the data and the bypass holding up before you commit. Client Testimonials: ⭐ "Noah is extremely helpful. He took the time to really show me how it worked, and ensured my first application worked. He did this on very short notice." ⭐ "I had the chance to work with Noah, and he was professional, always available, and willing to go the extra mile to get things done. A great experience working with him." ⭐ "Very satisfied! Everything was done exactly as agreed, and the delivery was extremely fast. Highly recommended!" 🛠 What I Build: - Authenticated extraction: login, session and cookie lifecycle, MFA handling, multi step workflows - Portal and dashboard automation: form filling, submissions, document downloads, status checks - Scheduled pipelines running headless on a server I set up and manage - Internal API discovery and reverse engineering, so the browser is only used where it has to be - Delivery into CSV, JSON, Google Sheets, PostgreSQL, Supabase or your own API - Repairs and takeovers of scrapers that broke or were abandoned 📌 Systems worth scraping are protected. I work inside environments guarded by Cloudflare, Imperva, hCaptcha and reCAPTCHA, browser fingerprint detection, rate limiting and aggressive session expiry, with residential proxy routing where the target requires it. 📌 Vendors change their interfaces without telling anyone Every system I ship includes a monitoring dashboard with success and failure analytics per run, so a change surfaces the day it happens instead of the week you notice the data stopped arriving. Most developers fix a scraper after it breaks. I build so the break is visible immediately and cheap to repair. 🔧 How I Work: I default to the simplest implementation that works. I do daily written async updates and weekly Loom walkthrough videos for my clients. 🛠 Technical Stack: n8n (self-hosted or cloud), Playwright, TypeScript, Node.js, Python, Claude (Sonnet, Opus, Haiku, Fable), GPT series, Gemini, Zod schema enforcement, React, REST APIs, webhooks, Docker, Supabase ⚙️ How It Runs: Your automations live on a server I set up and manage, running headless around the clock. If your project requires it, I will route requests through residential proxies so jobs complete reliably. Finally, I prepare a monitoring dashboard with analytics on all requests that both succeeded and failed. 👉 Who This Is For: Insurance agencies, healthcare and practice management, logistics, B2B data teams, and anyone whose vendor handed them a web login instead of an API. keywords: web scraping, browser automation, anti-bot, anti bot bypass, cloudflare bypass, imperva, captcha, recaptcha, hcaptcha, playwright, selenium, puppeteer, scrapy, beautifulsoup, python, headless browser, login scraping, authenticated scraping, portal automation, vendor portal, dashboard automation, data extraction, web crawler, etl, data pipeline, residential proxies, proxy rotation, session management, reverse engineering, api discovery, scheduled scraping, scraper repair, scraper maintenance, monitoring, insurance automation, carrier portal, practice management, healthcare data, lead generation, price monitoring, competitor monitoring, real estate, ecommerce

Hi, I'm Saima Ali, a web scraping developer who builds clean, reliable scrapers in Python. I extract data from any website (including login-protected, dynamic, and JavaScript-heavy sites) and deliver it in CSV, Excel, JSON, or straight into your database. A past client wrote: "Do not hesitate to use this gem of a programmer. She knows her stuff inside out." That's the standard I aim for on every job. If you've been frustrated with scrapers that break after a week, miss data, or return messy files, I focus on the opposite: structured output, stable runs, and code you can actually maintain. What I can scrape for you: 1) E-commerce product data (Amazon, Shopify, eBay, AliExpress) — titles, prices, SKUs, variants, stock, images 2) Real estate listings (Zillow, Redfin, Realtor) — property details, prices, agent info 3) Lead generation data — emails, phone numbers, company info from directories and business listings 4) Social media data — Instagram, Twitter/X, TikTok, YouTube profiles and posts 5) Google Maps business scraping — name, address, phone, ratings, reviews 6) PDF and document extraction — catalogues, reports, invoices into structured tables 7) Login-protected and infinite-scroll sites — sites others say are "impossible" to scrape 8) Existing scraper fixes, debugging, and stabilization 9) Scheduled scrapers that run daily/weekly with monitoring and email alerts My toolkit: Python · Scrapy · Selenium · Playwright · BeautifulSoup · Requests · Pandas · XPath · CSS Selectors · JSON · CSV · Excel · MySQL · PostgreSQL · MongoDB · Proxies · Headless browsers · Cron jobs · API integration How I work: 1) You send me the site(s) and the data fields you need 2) I check the site and tell you honestly if it's possible, how long it'll take, and the cost 3) I build the scraper and send you a sample output for approval 4) I deliver the full data + the script (if you want it) so you can re-run it later 5) Free fixes for 7 days after delivery if anything breaks I work fast most small jobs delivered in 24–48 hours. I reply to messages quickly and I won't disappear mid-project. If I'm not the right fit for your project, I'll tell you upfront instead of wasting your time. Send me a message with the website link and the data fields you need. I'll reply within a few hours with a clear quote and timeline.

I build production-grade Python-based data extraction and Web Scraping systems that survive where others fail. Projects range from focused data extraction tasks to large-scale Anti-Bot resilient infrastructures — each engineered for stability, performance, and long-term reliability. Over 12+ years, I’ve designed extraction systems processing 1B+ structured records across marketplaces, aggregators, AI/ML platforms, competitive intelligence systems, and enterprise catalogs. My systems are built using Python, Scrapy, Playwright, and Selenium — combining Web Scraper development, Data Mining, API Integration, and ETL pipeline design into stable, production-grade architectures. Whether you need a targeted scraping solution or a high-volume distributed pipeline, I architect the right system. When data becomes mission-critical — reliability matters more than code. ────────────── What I Build ────────────── • Custom Python Web Scraper and Data Extraction systems aligned with business logic • Scalable web crawlers handling anything from selective datasets to millions of pages • Continuous update pipelines (batch & incremental ETL workflows) • Queue-based distributed processing • High-concurrency execution models • API-based data extraction and system integrations • Clean ingestion into PostgreSQL / MySQL / APIs / cloud storage • Automated validation, deduplication & anomaly detection • Structured Data Mining pipelines for growing datasets You receive structured, business-ready datasets — not scripts to babysit. ────────────── Anti-Bot & Protection Layers ────────────── Modern platforms are protected.I work inside environments guarded by: - Cloudflare (403 / 429 / Turnstile) - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - Reverse engineering of detection vectors & TLS/JA3 fingerprint alignment - Headless & browser fingerprint detection - hCaptcha / reCAPTCHA v3 Enterprise - Sustainable session & token lifecycle management This is not proxy swapping. This is controlled, sustainable access engineering. ────────────── Scale & Cost Control ────────────── As volume increases, scraping typically fails in two ways: 1) Stability collapses 2) Infrastructure & proxy costs explode I optimize concurrency models, routing logic, batching strategy, request distribution, and traffic patterns to maintain high throughput with controlled infrastructure load. Where relevant, I reduce proxy and infrastructure costs by up to 30% while preserving system stability. Result: High uptime. Predictable performance. Controlled margins. ────────────── Future-Proofing ────────────── Websites evolve. Structures change. Protection layers update. I implement structural drift monitoring and heartbeat systems that detect site changes before pipelines fail — shifting from reactive recovery to proactive control. Most developers fix scraping after it breaks. I design systems that minimize breakage from the start. ────────────── Who This Is For ────────────── • Founders building data-driven products • AI/ML teams requiring proprietary datasets • Businesses automating competitive intelligence or market tracking • Companies where reliable data access supports growth ────────────── Confidence Check ────────────── If needed, I can provide a working sample before full engagement to demonstrate data quality and bypass stability. To get started, send: - Target website(s) - Required data fields - Expected volume - Update frequency - Preferred output format Whether you're starting with a focused scraping task or building a large-scale data infrastructure — let’s build it properly.
