Andrii H.

Python backend & scraping engineer who builds data pipelines that survive anti-bot updates — and full-stack apps that ship on time. 4+ years, production-grade code, no guesswork. I help businesses turn messy or missing data into structured, reliable systems — and turn ideas into working web products. Recent results: 📊 Real estate data scraping (UK) — built and maintained a large-scale system bypassing anti-bot protection on a major property aggregator, updating daily. Powers a Chrome extension used for rental yield & profitability analysis. 💬 Telegram referral bot (retail chain) — grew to 5,000+ active users; 4,100+ joined via the referral system alone, replacing multiple manual tools with one automated flow. 🔍 Industry-wide data aggregation (semiconductor sector) — coordinated scraping across 100+ websites with different structures and blocking mechanisms, normalized into one centralized database. 🧠 AI + scraping infrastructure (real estate) — built a RAG system that uses past scraping cases to auto-generate new scraper pipelines, plus a computer vision model that calculates apartment area from floor plans. Full DevOps on Azure. What I bring: ✅ Clean, maintainable architecture — not just "it works," but "it scales" ✅ Anti-bot expertise (Cloudflare, CAPTCHA, rotating proxies, headless browsers) ✅ Full ownership from API design to deployment and support Core stack: Python, FastAPI, Django, React/Next.js, PostgreSQL, Docker, AWS/Azure, Scrapy/Playwright/Selenium.
