About

AI engineer with 20+ years of full-stack depth, shipping systems businesses actually run — twelve of them owning the foundations of an enterprise case-management platform for a US software company, remote from China the whole time. I lead architecture and still write the code.

Recent years go into putting AI into production: OCR pipelines, deep-learning image analysis, LLM-powered features — delivered through a daily, process-disciplined AI-native workflow.

Remote, async-friendly, UTC+8 — comfortable overlapping US and European hours.
