Ross F.

Senior Python engineer building large-scale web scraping systems, reliable APIs, and LLM/RAG data pipelines that run in production — tested, monitored, and built to last. 🏆 Top Rated Plus (top 3%) · $300K+ earned · 7,400+ hours billed ━━━━━━━━━━━━━━━━━━━━━━ RECENT PRODUCTION RESULTS 🌍 Built and operate a scraping platform covering 20+ sources behind enterprise anti-bot protection (Cloudflare-class WAFs, residential proxy rotation, fallback transport chains) — 225K+ documents collected, 30+ scheduled pipelines running daily without babysitting. 💳 Built a rewards-data aggregator scraping 30+ retail and banking sources — 60K+ fresh offers per day, normalized into one schema and served through a load-balanced API at 105+ requests/sec. 🤖 Turned scraped-document chaos into structured data with a RAG extraction system (LLM + Pinecone) over 100K+ documents — measured accuracy up from 33% to 84%, every AI output traceable to its source. ━━━━━━━━━━━━━━━━━━━━━━ WHAT I DO ✔️ Web scraping & data extraction — Playwright, Selenium, Scrapy; resilient access to protected sources, proxy management, scheduled fleets via Celery, PDF/Excel/Word extraction, normalization into clean schemas ✔️ LLM & RAG backends — OpenAI/Anthropic APIs, Pinecone, vector search, structured extraction from messy documents, accuracy evaluation, cost & latency optimization ✔️ API development — FastAPI, Flask, Django; auth, rate limiting, background jobs, clean documentation ✔️ Distributed systems — Celery, RabbitMQ, Redis; retries, idempotency, fault tolerance under real load ✔️ Production ops — Docker, AWS, PostgreSQL/MongoDB/Neo4j, zero-downtime migrations, CI with 2,000+ tests per project ━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK ✅ I own systems end-to-end: architecture → implementation → deployment → monitoring → handover docs. ✅ Scrapers that keep working: per-source error recovery, alerting, and proxy fallbacks — not scripts that die in a week. ✅ I'll tell you when an LLM is the wrong tool — and what to use instead. ✅ Most of my $300K+ comes from repeat clients and multi-year engagements. ━━━━━━━━━━━━━━━━━━━━━━ If you need scraping infrastructure that survives contact with real anti-bot systems, an API that holds up under load, or an LLM pipeline with measurable accuracy — send me a message with a couple of lines about your project and I'll tell you straight away whether I'm the right fit.
