I build software that does engineering work.
Software engineer at Sargent & Lundy. I build production systems for engineering work: computer-vision drawing comparison that replaces manual page-by-page review, document pipelines that index tens of thousands of drawing sheets, and the Python standards the firm builds on. Python and TypeScript on Azure, with queue-backed workers doing the heavy processing.
