# about

For ten years I've built and run the systems that turn marketplaces into data — today extracting 15M+ prices a day and tracking 200k+ products across AliExpress, Amazon, eBay and Temu, with the anti-bot, captcha and proxy infrastructure that keeps it flowing. Go is my primary language, and I favor lean, dockerized services sized to the real load over infrastructure for its own sake. I don't just write parsers — I own them in production. Native Spanish, fluent Russian and advanced English let me work directly across LATAM, Russian-speaking and European markets.
