🏆 Top Rated Plus · $400K+ earned · 99% Job Success I design, build, and ship the web scrapers, data pipelines, AI/LLM integrations, and full SaaS products that other developers call "impossible" — and I stay on it until it actually works inside your systems, not just in a demo. Most freelancers hand you a script and disappear. I scope the real problem, build the full solution, and own the result until it's running in production and you can maintain it yourself. ⚙️ What I build for clients: - End-to-end products & SaaS — full builds, architected and shipped: backend, REST API, database design, auth, dashboards, deployment — complete systems you can run and grow, not one-off scripts - Web scraping & data extraction at scale — listings, real estate / timeshare data, leads, pricing — including anti-bot, JS-heavy, and login-gated sites - Data pipelines & enrichment — clean, deduplicated, verified data delivered where you need it (database, sheet, or API) - AI & LLM integration — OpenAI / GPT-powered extraction, document parsing (PDF → structured data), classification, and AI agents wired into real workflows - Third-party API integration — connecting platforms, syncing data, and automating the manual steps between them 🧩 Recent work: - Real-estate / timeshare data platform integrated with the Guesty API - Scrapers for energy-market and financial portals (anti-bot, structured output) - PDF → Markdown / structured-data extraction pipeline - Verified business-contact datasets for the hospitality sector - Subscription prediction service — Python, statistical modeling, automated data flow 🤝 How I work: direct communication (I reply within hours), clear scope before I start, and code you own and understand — no black boxes, no lock-in. 🔧 Stack: Python (Playwright, Scrapy, BeautifulSoup, Pandas, Flask / Django), OpenAI API, REST APIs, PostgreSQL / MySQL / MongoDB, Docker, AWS. 💬 Message me with what you're trying to achieve — I'll tell you straight whether I can help and how I'd approach it.
