A life in software.
I spent decades shipping software across the full spectrum: hedge fund audit systems at EY, sales and project platforms for Mitsubishi Electric, medical data integration at Johnson & Johnson, talent marketplaces for WME Group, cloud migrations for Napster, an iOS game Apple featured in “News & Noteworthy” worldwide, and a dozen others—always at the intersection of architecture and hands-on code.
