I am a web scraping expert with 13+ years of experience in Python-based data extraction from complex and Cloudflare-protected websites using proxies, Playwright, and custom-built scraping software. I specialize in scraping dynamic, JavaScript-heavy, and protected websites, including business directories, e-commerce platforms, marketplaces, and custom web applications. Depending on the project complexity, I combine custom Python scripts with proprietary scraping tools to achieve fast, reliable, and cost-effective data extraction. This allows me to efficiently handle both small one-time tasks and large, long-term scraping pipelines. I work with projects of any size — from quick one-hour jobs to complex, long-term contracts requiring continuous data collection, monitoring, and maintenance. I have extensive experience scraping a wide variety of websites, from business directories and lead generation platforms to large-scale e-commerce systems. This includes extracting contact data, company and people information, as well as structured product data from high-traffic online stores such as electronics, auto parts, furniture, and other complex marketplaces. Deliverables include clean, well-structured data in CSV, Excel or JSON

I am a Web Scraping developer with 2+ years of experience and 500+ production spiders delivered. I build stable and maintainable data extraction pipelines using Python. I work with dynamic websites, protected content (CAPTCHA / Cloudflare) and data that needs cleaning or structuring. I deliver clean, structured datasets (JSON, CSV, Excel, PostgreSQL/MySQL) and can automate full pipelines on schedule (Docker, cron). When needed, I also apply LLM for text parsing, classification and data enrichment.

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.

Hi, I am one of the best freelancer for web scraping / crawling / automated data extraction solutions on Upwork. I am doing web scraping jobs only and completed over 500 jobs and served hundreds of clients. My prices are more than reasonable and affordable compared to the service quality you will get, so please do not hesitate to request a quote if you need an expert scraper / crawler. I am developing my own custom program for each website I am going to scrap / crawl. I'm not using a pre-built software so i can adapt my program to any format and any website easily. There is no exceptional case, i can scrape any website using any technology (captchas, ajax requests etc.). I can provide scraped data in whatever format you want: csv, excel, xml, mysql etc. I can also provide you the program i used to scrape that website. I am developing my programs in java and you may run them on windows, mac and linux/unix machines. Up to now I developed applications to extract data from well known e-commerce marketplaces, search engines, business and local directories, real estate listings and many other websites. The work on Upwork is my full time job and not a side gig, so I dedicate a lot of attention to my clients, available to respond throughout the day, and work full days to complete the projects as fast as possible.
