Founders, CTOs, and operators hire me to keep engineers on product, not babysitting scrapers. I build and run these systems end to end: disconnected web and API sources fused into decision-ready data and market intelligence, with LLM judgment and AI automation built in. Classification, entity resolution, calls a regex cannot make. Built in Python. Run for years. No cost spiral. AI handles the easy pages now, and I will tell you when that is all you need. On hard sources, it fails quietly, or worse, confidently wrong. ๐—ž๐—ป๐—ผ๐˜„๐—ถ๐—ป๐—ด ๐˜„๐—ต๐—ฒ๐—ฟ๐—ฒ ๐˜๐—ต๐—ฎ๐˜ ๐—น๐—ถ๐—ป๐—ฒ ๐˜€๐—ถ๐˜๐˜€ ๐—ถ๐˜€ ๐˜๐—ต๐—ฒ ๐—ท๐—ผ๐—ฏ: ๐—”๐—œ ๐—ณ๐—ผ๐—ฟ ๐—ท๐˜‚๐—ฑ๐—ด๐—บ๐—ฒ๐—ป๐˜ ๐—ฎ๐˜ ๐—บ๐—ฎ๐—ฐ๐—ต๐—ถ๐—ป๐—ฒ ๐˜€๐—ฐ๐—ฎ๐—น๐—ฒ, ๐—ฒ๐—ป๐—ด๐—ถ๐—ป๐—ฒ๐—ฒ๐—ฟ๐—ถ๐—ป๐—ด ๐—ณ๐—ผ๐—ฟ ๐—ฎ๐—ฐ๐—ฐ๐—ฒ๐˜€๐˜€.

I track surgical-robot installs across dozens of countries and languages for a medical-device intelligence firm: press releases, regulatory filings, clinical announcements. An AI layer makes the judgment a plain scraper can't: real install, or just a demo?

Cloudflare, DataDome, PerimeterX, CAPTCHAs, login walls, rate limits, JavaScript-heavy apps, undocumented APIs. Python, Playwright, Scrapy, and rotating proxies get past them at scale. โ†’ Intelligence. Classifying records, resolving entities, making judgment calls at machine scale. Also RAG-ready corpora and ML training data: multi-source, deduplicated, embeddings-ready. โ†’ Reliability. Monitored, tested, still running months later, and delivered in whatever your stack expects: CSV, JSONL, Parquet, a database, or S3/GCS. Sources I have worked: court dockets, business registrations, federal import-tariff filings, Zillow, Trulia, county assessors and permit systems, multi-country marketplaces, 50M+ Instagram profiles, attorney profiles at scale. ๐—ช๐—›๐—ฌ ๐—–๐—Ÿ๐—œ๐—˜๐—ก๐—ง๐—ฆ ๐—ฆ๐—ง๐—”๐—ฌ Before building data systems, I spent five years in private banking at J.P. Morgan. In that world, a dropped ball is not an option, and I bring that exact standard to my engineering. The code is only half of what you get; the rest is absolute reliability. โ†’ Fixed price, every time. I quote it, you approve it, I deliver it. No hourly surprises. โ†’ Straight answers. If it is not a fit, or there's a cheaper path, you hear it first. โ†’ No handoffs, no disappearing.
