Need clean, reliable data from the web — delivered fast and ready to use? I'm a Python specialist with 5+ years of hands-on experience in web scraping, automation, and data extraction. I've worked with clients across e-commerce, real estate, finance, and lead generation — building scrapers and bots that handle everything from simple one-time extractions to large-scale, scheduled pipelines running millions of records. 🔧 Web Scraping & Automation (My Core Strength): · Custom web scrapers — e-commerce, real estate, Google, social media · Browser automation — Selenium, Playwright, dynamic JS-heavy sites · Scheduled & recurring data pipelines — auto-run, auto-deliver · File downloaders — images, PDFs, MP3s at scale · Anti-bot bypass — rotating proxies, headers, CAPTCHA handling · Output in any format — CSV, Excel, JSON, XML, Google Sheets 🐍 Python & Backend Development: · Django & Django REST Framework — web apps and APIs · Flask — lightweight APIs and automation services · Database design & management — PostgreSQL, MySQL, SQLite, Snowflake · Custom automation scripts — eliminate repetitive manual work What makes me different: I don't just write code — I ask the right questions upfront, deliver clean and well-commented scripts, and make sure the data you get is actually usable. No surprises, no delays. 📩 Message me with your project details and I'll respond within a few hours with a clear plan and timeline.
