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

Last 2 years I've been working as a Mac OS X developer. I have over 10 years of experience in developing SQL-reports, VBA. I've completed more than 600 Excel VBA projects on Upwork and Elance. I graduated from university majoring in Applied Mathematics. I am looking for challenging tasks, not copying existing solutions.

Hey guys, my name is Alex and I am web scraping and data mining expert with over 7 years of experience and hundreds of successfully completed project in my portfolio. If you are looking for a reliable and experienced professional - you are on the right spot! I work with websites and apps of any complexity and any level of protection. If the website contains data - I can collect it. Here is the list of projects I can help you with: - Collecting and analyzing price info(price comparison) - Tracking your competitor prices or sales(Amazon, Ebay, Etsy, etc) - Collecting contact information - Collecting starter product databases(like initial content for job boards, cars auctions, classified ads, etc) - Product information enrichment(ratings, reviews, descriptions, etc) - Collecting other publicly available data During my work with scrapping I have developed a convenient algorithm of interaction with customers, namely the subscription. Agree on the frequency of data delivery (from daily reports to 1 report per month). You do not pay for development of parser, proxy, servers, etc.; everything is already included in the tariff. I focus on long-term and mutually beneficial cooperation, so I do everything as quickly and accurately as possible. Please check my Upwork ready-made projects for details! Now I want to bring my expertise and solutions to the table to accelerate your business. Let’s create your next stunning projects together! 🏆 I am ready, let’s chat?

1000+ Scrapers Built | 1B+ Records Collected | 12+ Years Experience I build production-grade web scraping and data extraction systems that continue working where most scrapers fail. My work ranges from focused scraping tasks and custom web scrapers to large-scale data infrastructures designed for stability, scalability, and long-term reliability. Whether you need a small scraper, a medium-size data extraction tool, or a high-volume scraping pipeline — I design the right solution for your project stage, budget, and goals. You don’t just get a script — you get a reliable data collection system built around your business needs. I take full ownership of the technical data collection process so you can focus on strategy, growth, sales, or product development. Whether you're a startup validating an idea, a growing company building data pipelines, or an established business scaling large datasets — I design solutions that fit the stage and goals of your project. ============================== What I Build ============================== I combine Web Scraper development, Data Mining, API Integration, browser automation, reverse engineering, and ETL pipeline design into stable production systems. Core services: - Custom Python web scraper development - Web scraping and data extraction from public websites - Scalable web crawlers for large-volume data collection - Product scraper, real estate scraper, marketplace scraper, directory scraper, review scraper, price scraper, lead scraper, and business data scraper systems - Continuous data update pipelines - Batch and incremental ETL workflows - Queue-based distributed scraping architecture - High-concurrency crawling and data processing - API data extraction and backend integrations - Data cleaning, validation, deduplication, sanity checks, and anomaly detection - Structured delivery into PostgreSQL, MySQL, MongoDB, CSV, Excel, JSON, Google Sheets, APIs, or cloud storage You receive clean, structured, business-ready data — not fragile scripts that need constant supervision. ============================== Anti-Bot & Protected Websites ============================== Many modern websites are protected by advanced Anti-Bot and WAF systems. I work with complex scraping environments where stability requires more than proxy rotation. Experience includes: - Cloudflare protection, 403 / 429 errors, IUAM, Turnstile - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - Rate limiting and IP bans - Browser and headless browser detection - Canvas / WebGL fingerprint exposure - HTTP/2 and TLS / JA3 fingerprint alignment - reCAPTCHA, hCaptcha, and challenge loops - Session, token, and authorization lifecycle management - Residential and mobile proxy routing strategies The goal is controlled, sustainable data access with realistic traffic patterns, stable sessions, monitoring, retry logic, and long-term reliability. ============================== Large-Scale Scraping & Cost Control ============================== At scale, most scraping systems fail in two ways: 1. Stability breaks when websites change or traffic grows. 2. Infrastructure and proxy costs become too expensive. I solve both by designing the right architecture from the beginning: - Distributed workers - Queue-based processing - Smart batching - Request optimization - Proxy rotation strategy - Concurrency control - Database ingestion optimization - Error handling and retry systems - Monitoring and heartbeat checks - Structural change detection - Protection-drift monitoring Where relevant, I optimize proxy and infrastructure usage to reduce operating costs while preserving system stability and throughput. The result: High uptime. Clean data. Predictable performance. Controlled costs. ============================== Technical Stack ============================== Languages & Scraping Frameworks: Python, Scrapy, Playwright, Selenium, Beautiful Soup, Requests Data & Storage: PostgreSQL, MySQL, MongoDB, CSV, Excel, JSON, Google Sheets, APIs, AWS S3, Cloud Storage Infrastructure: Docker, Redis, Celery, RabbitMQ, distributed workers, queue-based pipelines, cron jobs, cloud servers Network & Anti-Bot: Residential proxies, mobile proxies, proxy rotation, HTTP/2 fingerprinting, TLS / JA3 alignment, CAPTCHA solving APIs, session management, browser fingerprint stabilization ============================== Typical Projects ============================== - E-commerce product data scraping - Real estate listing and agent data extraction - Marketplace and aggregator scraping - Price monitoring and competitor intelligence - Business directory scraping - Lead generation datasets - Review and rating extraction - Travel, hotel, ticketing, event, and inventory data collection - AI/ML dataset creation - Large-scale crawler development - Scraping infrastructure for SaaS, PropTech, FinTech, marketplaces, and data products
