I specialize in Python automation and advanced web scraping. Over the past 3+ years, I’ve built reliable automation systems that handle complex, real-world scenarios — not just basic scripts. My expertise includes: • Web automation using Python and Selenium • Handling dynamic and JavaScript-heavy websites • Bypassing common anti-bot protections (Cloudflare, rate limits, behavioral checks) • Automated logins, multi-step workflows, dashboards, and data extraction • Large-scale data scraping with structured output (CSV, Excel, databases) • Browser automation with Chrome DevTools and custom configurations I don’t just write scripts — I build stable automation solutions. Many websites break simple bots. I design systems that handle dynamic elements, token-based authentication, rotating headers, session persistence, and failure recovery. My focus is reliability and long-term usability. I also convert automation scripts into professional desktop applications using PyQt. This allows clients to run complex automation tools with a clean GUI, input controls, logging panels, and export options — without touching code. What you can expect from working with me: • Clean, well-structured Python code • Scalable and maintainable solutions • Proper error handling and logging • Clear communication • Long-term support If a bug appears or a minor adjustment is needed later, I fix it. I believe in building long-term relationships, not one-time transactions. If you need web scraping, browser automation, data extraction, or a custom automation tool built in Python, I can deliver a solution that works in production — not just in theory.
